Hi.

I found the firebase authentication extension (version 3) by mirxtrem. Its good. I have learnt to sign up, and sign in.

What about Sign out?. There is no way to sign out? Does firebase signout users automatically after a certain time?

Thanks in advance.

Use web component for (user signup, user login and user signout) :

There is no sign out using the extension (REST api) but it can be done using the web method above.

Sign in tokens usually have a lifetime of one hour. The authenticated user will be required to sign in again after the token expires, unless the developer provides a token refresh routine to keep them logged in.

I have used the extension by mirxtrem for the sign up, sign in, and delete.
Its great for these purposes.

question. When I use the delete user, from mirxtrems extension, the user record does not actually delete from he authentication list in firebase. is that by design?

I have also used and done the exercise here ->
https://ai2.metricrat.co.uk/guides/firebase-authentication-with-web-component-and-html

Main question.
How can I use a combination of both these resources. i.e use the extension by mirxtrem for what it can do. And use the webview/ web ... technique from 'metricrat ' for he purpose of logging off, signing out, of firebase...why would that happen?

also, thrid question - I was able to "sign in" even with a wrong password in the 'metricrat' version.

Humble thanks in advance.

In some situations, yes

See here:
How to have Secure Rules on Firebase, and allow Auth Users to Read/Write

Really? Are you able to repeat this and provide an example?

With regards to signing out, use your app to do that, so that the user HAS to sign in again if they want to return.

To enable "Logout", can we not do this?
Store the refreshtoke in a global variable.
On Logout button click, call FirebaseAuth.RefreshIdToken passing the token stored in the variable.
Set the variable to null/blank.
The FirebaseAuth.Error event gets called; if no errors, the event FirebaseAuth.AfterRefreshToken gets triggered. Here if the variable is null, set the expireIn to 0 or a small number like 5 (5 seconds).
This should log the user out of Firebase dB, right..on top of other app. level logout options
