I've been trying to create a new user in firebase with a custom UID in flutter, but it seems it only can be done using FireBaseAdmin package, and it hasn't been implemented yet in flutter. Is there's any possible way to create a new user with custom UID?
I have no background on native development, so it's not possible for me to implement the admin methods in native java or kotlin in the current time. any one has an idea on how to implement it?
The UID for a user is determine by the authentication provider that creates the user. There is no way to specify your own UID when calling to the existing providers in the client-side Firebase SDKs (such as the FlutterFire libraries).
If specifying your own UID for a user is a hard requirement, you can implement a custom provider. This does involve writing code to create a custom ID token that runs in a trusted environment (such as your development machine, a server that you control, or Cloud Functions) however.
Alternatively, you can also consider storing a mapping from Firebase-provided UID to the ID that you want to use to refer to that same user. This is a scenario regularly used to give users a unique name, so I recommend checking out questions related to unique user names.
You can use FirebaseAuthentication.
When a user create an account it will create a new user with a random UID and the UID will be unique. I assume that you can also specify you own UIDs

Its very easy to use :p

I need to send user-specific values to an external system from Moodle. How can I force Moodle to send the session ID (or user ID, activity ID, etc.) to this third-party system? All of the articles out there seem to be written for calling into Moodle but this is not what I need to do.
Important:
I cannot alter the Moodle installation. The solution must only involve editing content. This means I cannot author a new plugin or alter any of the Moodle source code.
Edit:
I do have direct access to the Moodle database from a separate external API. The goal was to use this connection to validate the incoming parameters. However, I still need to be able to construct a parameterized URL to call out the external app. That app would then be able to validate the supplied values against the database. If the session ID is not available then I would need the values regarding the page, user, module, etc. to be sent via the parameterized URL.
For the session id do you mean the current user session? There is a session key stored in $_SESSION['USER']->sesskey but its not really useful data. It expires when a user logs out.
$_SESSION is server side, so you would need to use PHP code which isn't allowed in content for security reasons.
Have you got access to the database? You could pull user id and activity id from there. Otherwise you will need to use an API or a plugin.
EDIT: There is a URL activity that you could use to send data externally. But that would require the user to click the link.
Data includes user and course ids.

I can't think of any solution to send data externally without writing some PHP code or adding a plugin.
You can add javascript to every page via Site administration > Appearance > Additional HTML but the session variables aren't available without PHP.

I'm developing app for University. I will give each student a unique 10 digit Id for login(no email and password, student can just login using the given id). Now I need to restrict student to access only their data, not other students data. In firestore security rules is it possible with my implementation?
In PHP MySQL I can check it in the script, in Firebase it is still possible if I use cloud functions for all read and write operations. Is it is good practice to use cloud functions for all read and write operations?
As long as you mint a custom token for your users, Firebase Authentication will know about the user, and pass the information into the security rules of your database. Without such a custom token, there is no way to pass your information into security rules.
I'm investigating a migration process from a legacy system into keycloak. Based on some of the ideas here: https://github.com/Smartling/keycloak-user-migration-provider we're looking to create user accounts in keycloak at the point of login by looking up user credentials from some dedicated endpoints on our legacy system.
As part of this, I need the user ID to remain the same as it was in the legacy system.
Is it possible to create a user with a specified ID rather than relying on keycloak to auto-generate it?
Running into this issue when attempting to create users via the API, I looked into the code for the users service. It looks like it is currently not possible to set the user id due to how the user is created.
From the code in https://github.com/keycloak/keycloak/blob/master/services/src/main/java/org/keycloak/services/resources/admin/UsersResource.java specifically on line https://github.com/keycloak/keycloak/blob/7cfe6addf01676939206e034a87c791460031032/services/src/main/java/org/keycloak/services/resources/admin/UsersResource.java#L115 the user is first created using the username, then updated. I believe id is not an updatable field. Thus it is not currently possible.
Checking the api I see it is now possible to add an optional "id" field in the userRepresentation object that you pass to create a new user in keycloak.

I am building a web-app with Meteor and i am using the Meteor Accounts-password package and accounts-facebook package to make login easy. The user has some information tied to them like email & password, but i want to tie more information to them after the account has been created.
I know of two ways that i could do that and i was wondering how i should do it, since i can't seem to find any information about it on the internet.
Option 1:
I add all the additional information (like username, displayname and other stuff) inside the Meteor.user.profile object. This seems to be a bad solution since users by default have access to everything in the profile object and i have to manually deny them access.
Option 2:
I create a new collection, Profile-information, and store all additional data about the user and then tie it to the meteor.user object via some shared key. This also seems like a bad solution since i have to split my data like in SQL and not have all the advantages of embedded documents in mongodb.
This has been my thought process so far and i am at a loss of how to continue.
Which option seems to be the best way, or is there an option 3 that would work better?
Thanks in advance.
Thanks to #forallepsilon i found out that you could write any data to the user object you want. I previously though that the user object was locked, and you could only store additional data in the profile field.
I will store the additional data i have about the user inside the Meteor.user object by just creating additional fields.
I want to implement database authentication in mongodb.
In order to do that, I found out that I need to first create an admin user and then create separate users for each of my database through mongodb client shell (manually or using a javascript file).
I was wondering if it is possible to add user to the individual databases from the spring application itself but did not get any useful pointers to do this. Is it that this approach is wrong because if this possible the application will always be able to access the database because it itself is creating the user, but external access will still be blocked.
Please let me know how this can be achieved or if it is an incorrect approach.
After you add a normal user via the MongoShell, you can then connect via your application and create either normal users, or read only users.
Note that a normal user can also add users, so the users your application adds may need to be down as read only users depending on your use case and needs.
In the MongoShell, adding a read only user can be done via
use myAppDB
db.addUser("JohnSmith", "CheddarCheese", true)
