How do I make AutoLogin?

Hello,a im making chat app, and i tried to make that you only have to log in once and then it logs itself. How do I do that?

I tried to do that with TinyDB, but it didn't work for me, or i don't know how to use this.

P.S. I used FirebaseDB to create login function.

For a specific device, you can use tinydb to store the login credentials, then return these at runtime (when the app is opened) to "automate" the login.

Without seeing your relevant login blocks for firebase it is difficult to advise further.
