Login Persistance in Firebase (V9)

Question

I have been reading the user documentation for browser login Persistence at Google Documentation . However its not clear enough, on what I should be doing for v9. Briefly here's what I understood. There are three types of persistence's: Per Session, Per Browser, and None. So now what I wanted to do was set Persistence for "per Browser". I saw two functions being used, one is inMemoryPersistence which I assumed to be per Browser and the other to be browserSessionPersistence which i assumed to be "per Session". However even after trying with both of them, after closing the tab and reopening its sends me to the login page.

 const auth = getAuth(); setPersistence(auth, browserSessionPersistence).then(() => { // Existing and future Auth states are now persisted in the current // session only. Closing the window would clear any existing state even // if a user forgets to sign out. //... // New sign-in will be persisted with session persistence. return signInWithEmailAndPassword(auth, email, password); }).catch((error) => { // Handle Errors here. const errorCode = error.code; const errorMessage = error.message; });

My code is just the same as what's provided in the docs, with browserSessionPersistance being one of two parameters I tried. So my question is:

1. Is my understanding of the 3 Types Correct?
2. If it is, then why isn't browser persistence working?

(Also I'm using Vanilla Javascript with Modular Import)

Answer 1

If you want to persist auth state and required explicit logout, use browserLocalPersistence .

Version V8 firebase.auth.Auth	Version V9	Description
Persistence.LOCAL	browserLocalPersistence	Explit logout required
Persistence.SESSION	browserSessionPersistence	current session or tab, cleared when closed
Persistence.NONE	inMemoryPersistence	in memory , not persisted, cleared when page is refreshed
