Dialogflow getting username from Gmail account in inline editor - google-cloud-firestore

I have a Dialogflow inline, where when welcome intent is executed I need to call agent.add() so it replies with something like
Hello (username)!
This username is not that the user writes but it's the profile name that he has logged in to the device

In order to get the user's name, you need to request permission from the user. So it usually isn't available as part of the welcoming Intent (at least not the first time they talk to your Action). You need to do one of two things:
Request user information which includes the user name. Once you have requested this information, you can save it so you'll get it the next time the user connects.
Ask the user to sign in. Once they have done so, you'll get an identity token with each request that includes the user's information

Firebase: Standard User Registration/Activation Workflow

I need to implement a standard user registration/activation workflow with Firebase. There doesn't seem to be an obvious way to implement this. When I say "standard", I mean how most email/password accounts work - not necessarily specific to Firebase. I'm sure you're familiar with this. This is the workflow:
User enters their username/password on a form with some validation and submits details
The back-end creates the user record in the database, but the account remains deactivated (i.e. user cannot authenticate - the activated flag is set to false)
The back-end sends an email to the user with a link to activate the account
The user clicks the link in their email which triggers activation. This is probably a Web API of some description.
At this point, the user record's activated flag ticks over to true, and the user can now authenticate
The link probably also has a deep link that opens the app or navigates to a web page
The user can now log into the app
How do I configure Firebase to do all this?
Currently, the app allows the user to register. I am using the Flutterfire SDK. I call createUserWithEmailAndPassword, which successfully creates the user in Firebase. But, the user is already activated. The user should have a state of "disabled" in firebase until the account becomes activated. I can't find any settings to default the user to disabled when the account is first created.
I also managed to get Firebase to send out an activation email by calling sendSignInLinkToEmail, but this call is really designed for email authentication - not email activation. Opening the link should activate the account, but I have not figured out how to do this. This documentation makes it sound like it is possible. Perhaps, the Flutterfire SDK is missing this? I don't want to allow people to log in without a password. I only want to use this call to send out an email.
What am I missing here? Is this non-standard behavior for Firebase? If so, why? If the user is allowed to use an app with an email address that is not activated, they can impersonate someone else. We need to confirm at least that they are custodians of the email address that they are claiming to have.
Do other Firebase people just not worry about this?
Lastly, I know I can achieve this by creating a collection for users in Firebase and putting an "activated" flag there. But, if I do that, I've got to write a cloud function that accepts the link and then updates the user in the collection based on the received link. But I thought this would be automatic in Firebase. If Firebase doesn't have this built-in, I have to put all the security over the top to stop users from authenticating when they have not yet activated their account.
This is a pretty valid concern. I suppose the way around this is to check whether the signed-in user is verified whenever the app is launched. The User object that is returned from Firebase Auth has an emailVerified flag. Check this page for more details.
Using this flag you can choose to show a different screen or pop-up that has a button to send a verification link to the registered email address. Until the user verifies this address, you can limit access to some of the app's screens if you want.
Please note that I have not checked if this emailVerified flag is true for sign ups using Federated login providers like Google Sign-in and Apple Sign In. You might want to check that out.

Can you send a link to the specific page where a user resets their password via Keycloak's API?

We have a PHP/MySQL based User Management System and are integrating it with Keycloak version 16 where we will store users credentials.
Our application does not allow users to self register. We create user accounts on the system. When we do this we do NOT specify a password because we want users to set up their own password.
The current system sends 2 separate emails in 2 different circumstances regarding passwords:
If it's a completely new user who does NOT have an existing password, we send them a link to set up a password.
If it's an existing user who already has a password, the system allows them to reset it, e.g. if they forget their password and can't login.
Keycloak seems to cater for scenario (2) because the login forms have a forgotten password link which opens a form where the user can enter their email address and receive a link which lets them do (2).
Unfortunately it doesn't deal with scenario (1) very well and that's where our problem starts. This has been asked a while ago Send password forgotten mail but it seems that Keycloak didn't support this very well in 2020 and perhaps still doesn't now.
Our "workaround" to this was that we added custom email templates and a custom page (reference: Themes on https://www.keycloak.org/docs/latest/server_development/#emails) which includes wording that caters for both scenarios, e.g. "set your password" rather than "reset your (existing) password". The result of this is that our email and form now reads appropriately for both scenarios (1) and (2).
The problem
We want to be able to send a link to the user that allows them to set their initial password to cover scenario (1).
We know that this page exists because on the login page for Keycloak there is a link to the forgotten password form that handles scenario (2). However, the form requires the user to enter their email address and submit the form. The user then receives an email from Keycloak which contains a URL to the page where they can do this. The URL has the following format:
https://example.com/auth/realms/foo/login-actions/action-token?key=...
The key= contains a ~945 character token. Going to the URL above redirects to the form where the user can reset their password. This next URL does not contain a token but a cookie has been set in the browser - by the previous URL - which makes it functional:
https://example.com/auth/realms/foo/login-actions/required-action?execution=UPDATE_PASSWORD
We can't send either of these URLs to the user because the first one (containing key=) has no API method for us to find out what it is - it's only possible to generate this by going through the "forgotten password" step during login, in the browser.
The second URL (/login-actions/required-action...) won't work either because it relies on the previous URL (containing key=) setting the cookie in the browser. If you try and go to this second URL directly (i.e. bypassing the first URL) it will error.
So neither of these URLs will work because we can't find what the first one is programmatically, and we can't use the second one without knowing the first one.
I found https://lists.jboss.org/pipermail/keycloak-user/2018-October/015910.html and the suggestion is using the Keycloak API to trigger a password reset email. This works - sending an HTTP PUT request containing 'UPDATE_PASSWORD' along with the relevant user ID sends the user an email. The request endpoint has the format PUT /{realm}/users/{id}/execute-actions-email which is documented on the link above.
Up to here all is fine - the user gets an email. However, this email does NOT contain a link that goes directly to the "reset password" page! Instead it sends them an email containing the following text:
Your administrator has just requested that you update your account by performing the following action(s): Update Password. Click on the link below to start this process.
Link to account update
When the user clicks "Link to account update" it then shows them a web page like this:
It is only when they click on the link on this page (the one that says "click here to proceed" on the screenshot) that they arrive at the form where they can reset their password.
This is a really poor user experience because the user gets sent a (badly worded) email with a link to... a page with another link! It should just take them to the password reset page directly. What's more frustrating is the fact that Keycloak is clearly capable of generating/sending the exact email we'd like in this scenario: the one which gets sent when a user manually does a password reset via their browser.
So the problem seems that Keycloak's API doesn't support this incredibly important and common use-case of a user being able to set an initial password, in a user-friendly manner.
I am adding the js script in the template to automatically click "click here to proceed". It's ugly but at least the user doesn't see the page

User data in event for Facebook server to server

I plan to generate Facebook events (Conversion API) on server side when the user completes registration process. These events will be used for advertising my solution in Facebook and tuning target audience on registration events.
I use POST request to https://graph.facebook.com/v9.0/289777498957502/events to send events. I have to pass user_data entity inside a body of this request. This user data can be email address, click id, user IP address or something else.
I don't have any of these on server side but I can get it.
The problem is that I don't understand why Facebook needs user data and what exactly it needs as data. I can send everything to Facebook but I need to understand mandatory information it requires.
Do you know what should be sent as user data?
As an option I can send internal ID in my system of each user inside user data but I'm not sure Facebook will be happy with that.
Facebook manuals are a pure joke. Literally all are outdated and no information on user data content and why it's required.
The problem is that I don't understand why Facebook needs user data
Because your conversion is (ideally) supposed to get connected to an actual user account. Facebook knows, who the user is, as long as we are on the client side, and their pixel is embedded somewhere - they can make the cross-domain requests in the background, to see who is currently logged-in to Facebook on the device. But if you send conversion data later, from your server - how would they be supposed to associate that with a specific user then, if you don’t send them any data that could identify one?
and what exactly it needs as data.
If you have anything that can uniquely identify the Facebook user, then send that.
Otherwise, send as much data as you can – to increase the posibility, that Facebook will be able to match this to a specific individual.
Check the list they provide under https://developers.facebook.com/docs/marketing-api/conversions-api/parameters/customer-information-parameters
If the user is logged in to your Facebook app while they are on your site, then send the fb_login_id – that is as unique and specific, as can be.
If you don’t use Facebook login on your site, or the user can also perform the action in question without being logged into your Facebook app - then send whatever you have, that identifies them on your end.
In case no unique match is possible, then send as much as possible - first & last name, phone number, date of birth - all those help to narrow down who the user might be on Facebook’s side.
The same data, or at least as much of it as is available at this time, should also be send with the pixel tracking code on the client side already. https://developers.facebook.com/docs/facebook-pixel/advanced/advanced-matching/ has details on that.

How to linking a users data to his future account at the time of signup in Stitch

I would like to use Stitch to sign up users. Each user must have a unqiue email and a unique user-name.
This is important for applications like chats or forums, where users should not be forced to reveal their email when communicating.
I already implemented login with email and password as described here: https://docs.mongodb.com/stitch/authentication/userpass/#authenticate-a-user
The problem is:
How to securely save a user-name on signup? I could store a users desired name in a collection and merge it into his custom user data after initial login. In order to do that, I would need to grant the user write privileges to whichever collection holds pending names. This is unsafe, since he could now change the name after the fact or even change other peoples names while they are pending.
The user needs to choose his name at the time of signup. At this time the user is still logged in via anonymous credentials. Hence, I can not restrict users to changing only their own data since they are at this point sill anonymous. I see no way of linking a users data to his future account at the time of signup. Any idea to change that?
It would seem strange, if stitch lacked the functionalities to easily sign up users with a unique name/handle in addition to email address.
I haven't used your exact software but in general I would approach the problem as follows:
When someone starts using the application anonymously, create a user object. The user at this point does not have a reserved (i.e. globally unique) user name, or email address, etc. But the user still has an internal identifier.
Associate user-visible state with the user object. This could be done through server-side sessions or signed cookies. (Unlike unsigned cookies, cryptographically signed cookies permit server to store what would otherwise have to be stored in the server-side session in a cookie, and trust that the client hasn't tampered with the information by e.g. changing the user id).
When user registers, set the user name, email address, etc. on the existing user object. User id remains the same and allows the user to continue to have access to their anonymously-generated data.
Have a process for deleting anonymous users that don't register after some time.

How to get email and username when Facebook registers

As far as I know, on the new Facebook API, there is no way to get the Facebook username. Also, if the user registered to Facebook, his or her account might lack an email address if he or she logged in with a phone number.
However, I am working on a project, where, upon login with Facebook, if the user does not have a user, then the Facebook login is interpreted as a registration. Since, according to my best knowledge, there is no way to get the Facebook username using the API, I am using the email field to generate a username, taking into account only letters.
However, in some cases, the username generated this way is duplicated, or the Facebook account does not have an email address. The best solution I can think about is to redirect the user to a form where he or she can enter the email and/or the username, but that would not help the user-experience.
Is there a way to gather these data without making the user enter them? Or something close to it?
First of all, you should always present the data you want to store to the user BEFORE you store it, and let him change it.
That being said, the (App Scoped) ID is the only thing that is really unique, you can either use the email directly (if the user is already registered, just add the Facebook ID to your database) and present an input field if there is no email - or generate a username with his first and last name. Present the chosen username to the user and let him change it, or tell him that it already exists.
After all, wouldn´t a user WANT to choose his username?
If you want to make it smooth for the user and don´t want to bug him in anyway, you can just store his Facebook ID. Or just use the email directly as username (including the # sign and the domain), as i wrote above. If that´s not good enough, you need to implement your own routine to auto-generate usernames. There´s no general logic from Facebook to do this.
