Email confirmation best practices for mobile apps - mobile

So I'm writing a mobile app and have reached a point where I need to allow users to register a username. I'm doing this by asking for an email address, username and password.
Typically, it's been normal to set this sort of thing up on the web by having the user confirm his email address by clicking on a link sent to his inbox.
Needless to say, on a mobile app this is a bit clunky as the user will be redirected out of your app and into his browser.
So I had a look at how other mobile apps are doing it (WP7) and was surprised to see that DropBox and Evernote both allow you to sign up without confirming your email address. The end result of this is that I was able to sign up with completely bogus email addresses and/or valid email addresses that don't belong to me.
I assume this is done on purpose.
Your thoughts?

I came across the same issue when writing a social networking style app. I chose to have the user create a username and then provide and email and password. I do not verify the email address and I've never attempted to send any email to them (yet).
What I would suggest would be alternate ways to validate a users email address. My app allows users to do Facebook Connect. All they have to do is log into Facebook, and the app talks to Facebook to confirm that they are using a valid email address. No need to verify it with a URL in an email.
I believe Twitter has a similar service and there may even be a few others that provide an API.
I've also discovered that a lot of people just want to tinker around in the app and not create an account at all. It's definitely a balancing act

I'd say it depends on your app and how important it is to ensure users have valid email addresses. In an app I'm creating now, we want to discourage users from signing up with multiple bogus accounts (because our system could be gamed that way) so we're not allowing users to log in until their email address if verified. On other sites however, it might not be such a big deal so why bother users with that extra step?
As for a mobile device, I don't see why you can't still send a verification email that sends them to your website to verify their email address. There are plenty of mobile apps that also have a website users can log into to manage their account.

Another option is have multiple "states" for users. Before they validate their email, they are in a "pending" state. Once they click it, they're in an "active" state. If you store the createDate for the user, you can periodically remove pending users older than 1 week (or however long).
The bonus is that you can easily add more states, such as suspended or deleted.

Personally, I wasn't too happy for users to create accounts with any old email address.
I think a few decent options are:
send a confirmation email with a link that uses a Custom Url Schema to redirect back to the app (although this is only good if they use the link on the same device)
send a short PIN in the email for them to enter back in the app.
send a confirmation email with a web link, have your server confirm the valid email/token, and have your app check the account status either periodically or with some sort of realtime tech like SignalR or Firebase.
I prefer the last one, although hardest to implement. A user might well have their phone in their hand and their laptop next to them, register in the app and try to click the link in the email that just showed up on their laptop. I like the idea of the app then just "knowing" that they've validated.

Do you have a web server? Write a web service that does the validation for you on the server side, and sends back the result.

Either you can use some platform, such as Facebook connect as #Brian replied above, or you may give users a reasonable timeframe to verify, for example, a few days or even a week. After that, the account gets removed.
You can even have your app issue notifications to remind the user to verify his account (such as every day, or on the last date of the verification.

Don't ask for email confirmation on mobile and allow the user to use the service. When the user is using a PC, then ask the user to confirm his email.
I won't defend my recommendation because most of the solutions here are valid. There isn't one correct way. You asked for ideas and here's one.

A good strategy is to allow people to use as much of your app as possible given the amount of data they've provided.
For example, in the case of a newsreader you might let someone browse your app without registering, then require an account for offline syncing, and a verified email for alerts. Always give people a good reason to take the next step, and build engagement first, then people will forgive you pestering them later.

Firebase, Changing User password via Email with unique password requirements

Currently, Firebase offers the option to send an email to a users email who wishes to change their password. Unfortunately, Firebase does not allow you to edit their password requirements which I believe is locked at requiring only 6 characters.
For many people this is inadequate and insecure.
I recently made an application that allows users to create quizzes either for themselves or for others. In this application, I stores personal information of my users and I wanted to make sure that their accounts were secure so I required more from my passwords. Unfortunately, when a user wishes to change their email, the default Firebase function does not keep my security which leads to confusion as a user can change their passwords according to Firebase's lax constraints but then they still couldn't log in because they used an invalid password. (I blocked invalid passwords from the text box before even checking with Firebase).
After I encountered this error, I came to StackOverflow for help to see if anyone else had this issue and came up with a solution. Unfortunately, I was met with harsh criticism and harassment by users who claim to be Firebase officials and Administrators who did not care about my question.
Then, I after a week of research and testing, I found the solution using React and 3rd party libraries to handle this.
Please, see my answer below and if you have a more creative solution, I would be interested in seeing that as well.
To solve this problem, the only answer is to create your own mailer service with your own basic mailer service, host website, and API.
What you need:
An application which uses Firebase.
A hosted API which uses Firebase and a 3rd party Mailer such as Node with NodeMailer - hosted on Heroku
A React app which can communicate with the API
What I did:
First, I created my API which accepts calls from my specified IP addresses. This API can receive requests to reset a password when the password is known or unknown. When the password is known, I send an email to the user using NodeMailer and I send a special HTML file so the email looks official. It is quite easy to copy the layout of Firebase's emails if you wish.
More Info can be found here: https://nodemailer.com/message/
Then, I created a React App that is hosted on Heroku. When the user clicks a link in the email, it will send them to this website with the required information in the query. This app, much like when the Firebase link is clicked is just a simple text box and submit button. However, now you can customize it to require password confirmation with a second text box. You can also add a company logo and custom colors so it isn't so HTML 1 looking like the link you see from Firebase. Most importantly, you can now control the password that the user enters to add your unique requirements.
On submit, the app will send the new password, username and old password if available to the API.
If you do not know how to create a React App or a Node API, you can see a detailed tutorial here: https://www.techandstartup.com/tutorials/build-api-with-node-express-and-mongodb
Finally, the API can log into the users account if a password is present and then change the password. Detailed steps can be seen from: https://www.codegrepper.com/code-examples/javascript/firebase+user+change+password
If a current password is not present, then the API can delete the user and recreate it with the desired password. Deleting a user can be seen: https://www.codegrepper.com/code-examples/javascript/firebase+delete+user Then you simply recreate a user. Example code: https://www.codegrepper.com/search.php?q=firebase%20createUserWithEmailAndPassword
With these steps, you can now send a password reset email to a user. The email will be completely unique as you will be designing it yourself. The password will be to your exact specifications as your React App will control the data on submit. And the page itself will look much more user friendly as it's not the default Firebase page.
Hopefully this helps you or your company with working around the Firebase reset password with email function. I am still holding out hope that another user may have a more elegant or basic solution than this as creating an API and hosting a website just for 1 function is not appealing in many cases.

Salesforce Server-to-Server integration without any user involved

I am working on a integration with Salesforce using REST APIs and, as part of the project, I need to send updates to Salesforce and these updates are not user triggered, they are system triggered.
Because of that, what I expect to see on Salesforce Field History is not a user name but the name of our Connected App (the app that made the update).
What I see today is the user name because the way the integration was made initially using OAuth Authorization Code flow.
To change that part of the project, I followed the link (OAuth 2.0 JWT Bearer Flow for Server-to-Server Integration): https://help.salesforce.com/articleView?id=sf.remoteaccess_oauth_flows.htm&type=5
Making that, I was expeting to generate a token for a System, not for a User, but that's not what happened: when I used the token generate from the JWT Bearer Flow and ran the update, the Field History still shows the user name.
What could I do then?
Which are the options in Salesforce to achieve the behavior I'm expecting?
The most important, in my opinion, is to have a Token for our system, not for a user.
Thanks!
Everybody is an user in Salesforce. Even if you access unauthenticated pages (some contact us form? case or lead capture) - it gets tracked under special Guest User.
It sounds stupid but gives you unified interface to control permissions (Profiles/Permission sets). You want guests to access only FAQ articles and make cases? Sure thing, do it in profile, don't get paranoid about people trying to guess right URLs. You think an app was hacked? You can terminate the session just like any other "user". Want to allow login only in certain hours and from certain IP? Sure.
An app connecting with JWT will still need username (main difference being it's "just" certificate for signing the request instead of password).
Your best bet is to create dedicated "Mr System", "SystemX integration" account. It sounds like waste of license but in the long run saves you questions "why did you edit my account at 1 am" and you could even use it as backup account if you use SSO and it ever fails...

Salesforce: How to automate report extraction as JSON/CSV

I am new to Salesforce, but am an experienced developer. I am provided a link to a Salesforce report, which mostly has the right filters (query). I would like to use an REST API to pull that information as CSV or JSON so that I can do further processing on it.
Here are my questions:
Do I need special permissions to make API calls? What are they?
Do I need to create an "app" with client-key & secret? Does my admin need to grant me permission for this too?
There are a lot of REST APIs from Salesforce, which one do I need to get the info from the report? Analytics?
How do I authenticate in code?
You'd have to work with the System Administrator on the security pieces. Anybody who knows how the company works, can all users see everything, is there Single Sign-On in place, how likely is the report to change...
You will need an user account to pull the data. You need to decide if it'll be some "system account" (you know username and password and have them stored in your app) or can it run for any user in this org. It might not matter much but reports are "fun". If there will be data visibility issues 6 months from now, you'll be asked to make sure the report shows only French data to French users etc... you can make it in report filters or have multiple reports - or you can just use current users access and then it's the sysadmin that has to set the sharing rules right. (would you ever think about packaging what you did and reusing in another SF instance? Making a mobile app out of it? Things like that, they may sound stupid now but will help you decide on best path)
The user (whether it'll be system account or human) needs Profile permissions like "API Enabled" + whatever else you'd need normally ("Run Reports" etc). If you're leaning towards doing it with system user - you might want to look at Password Policies and maybe set password to Never Expires. Now this is bit dangerous so there would be other things you might want to read up about: "API only user" (can't login to website), maybe even locking down the account so it can login only from certain IP ranges or at certain times when the job's supposed to be scheduled...
Connected App and OAUth2 stuff - it's a good idea to create one, yes. Technically you don't have to, you could use SOAP API to call login, get session id... But it's bit weak, OAuth2 would give you more control over security. If you have sandboxes - there's little-known trick. You can make connected app in production (or even totally unrelated Developer Edition) and use client id & secret from it to login to sandboxes. If you create app in sandbox and you refresh it - keys stop working.
(back to security piece - in connected app you can let any user allow/deny access or sysadmin would allow only say these 3 users to connect, "pre-authorize". Could be handy)
Login - there are few REST API ways to login. Depends on your decision. if you have 1 dedicated user you'll probably go with "web server flow". I've added example https://stackoverflow.com/a/56034159/313628 if you don't have a ready SF connection library in your programming language.
If you'll let users login with their own credentials there will be typical OAuth "dance" of going to the target page (Google login, LinkedIn, Twitter...) and back to your app on success. This even works if client has Single Sign-On enabled. Or you could let people type in their username and pass into your app but that's not a great solution.
Pull the actual report already
Once you have session id. Official way would be to use Reporting API, for example https://developer.salesforce.com/docs/atlas.en-us.api_analytics.meta/api_analytics/sforce_analytics_rest_api_get_reportdata.htm
A quick & dirty and officially not supported thing is to mimic what happens when user clicks the report export in UI. Craft a GET request with right cookie and you're golden. See https://stackoverflow.com/a/57745683/313628. No idea if this will work if you went with dedicated account and "API access only" permission.

Signup for email accounts from GAE app

I am faced with a rather strange request and there isn't much material online tackling that.
I am building a web app on GAE ... front end, back end, datastore, blob store, user accounts, the whole nine yards ...
Part of the requirements is to have a user communication system, (users sending messages to each other, just like Facebook) as user emails are not to be shared among other users, and the web app shall only send emails to the user sign up email strictly for security and administration purposes, and wont flood their inbox with notifications like some websites do.
I have narrowed narrowed it down to 4 options
Option 1:
Reinvent the wheel - Build this whole system form scratch on the Datastore and Blob store. However, not only is it expensive, but also I am not gonna go through all of that (just saying honestly)
Option 2:
Build a bouncing system ... User A sends message to app ... app bounces email to User B. Not very Elegant, impossible to create threads and conversations, eats up app Mail Quota used for Marketing and what not.
Option 3:
Host My own Email server onsite. Patch an API servlet and run the whole show through API. Very valid, except that the client doesn't want anything on site, and I wont be around to maintain it for him.
Option 4:(Best option if someone helps out)
Implement option 3 on a 3rd party email provider. Which brings us to the question, is there any respectable email provider that allows account sign up through API ?? I need to create a shadow email account on a 3rd party server(that the user will never know it exists) every time someone makes an account on my app. Then store all emails and their generated passwords in the Datastore, and when user logs in my web app, web app logs in 3rd party server, retrieves messages and serves it. When he wants to send a message, web app gets the message, sends an email using API as well. If someone knows how to do that on Gmail, I would be eternally grateful (but I highly doubt google allows that)
Note
I can implement the whole setup on xmpp/Jabber servers as well but these free servers keep changing all the time and they change their configurations ... bottom line they are not very reliable.
Thanks a lot guys !! I really appreciate any feed back and if you have any other suggestions please don't hesitate !! This is by no means a solid plan yet.

java googlemail blocks multiple access

I need to allow a user of my App to email themselves when an even occurs. I am not sure how to do this.
My first idea is to create a dummy gmail account, and have my App sign-in and send from there via java code. This means hardcoding the password BUT as account not used for anything other than one way emailing - it does not seem to be a problem.
However, I understand that google is pretty proactive about security and if my App (which is global) tries to log into same account in several different countries during a 24 hour period - it will block the email.
I have seen the "delegate" functionality, but that would mean that each user needs their own gmail account which is not practical.
Is there a way to force gmail to allow the sign-ins to happen from wherever?
Or is there a better approach to this problem?
probably not a good idea to have your app to mail from a private account, if I understand you correctly. Best to use email service like http://expresspigeon.com or http://sendgrid.com and simply send a transactional email from your app account. In other words, use an ESP.
The safest would be to ask the user for all the configuration information necessary to access their email server as themself, then send the email as themself to themself. You can use JavaMail to send the message, but you'll need to ask for all the configuration information that any other email application would ask for in order to configure access to their mail server.
There may also be Android-specific ways to do this using the default email application.
