Im develop a app. I'm using firebase and flutter. But now i would change from firebase to my own database (node.js).

Here my question:

• Is it possible to use the firebase user authentication with my own database?
• Or need i host a own smpt server to send the verification emails?
• Is it possible to 'keep the user login' without firebase?
• How i can do that?

If you have any question to me feel free to ask me. Many thx (:

Yes, you can use Firebase Authentication with your own database, or other backend service. You will need to implement your own server-side code that verifies the ID token from the client, and then ensures that the client is authorized to perform the operations it requests.
