Thanks for providing this. Question why do you need signinSilent? signinRedirect and signinPopup are the natural choices. where signinSilent is used behind the scene to automatically update, which is already handled with useAuth...

Hello @pamapa ,

excuse me for the late answer - unfortanetly I was ill and thus not able to answer asap.

We mostly use signinRedirect and ocassionally signinPopup. So as you said, we too only need these.
I just added the signinSilent as option, because I was unsure if there are other cases I overlooked or you have special needs for. Thus I just tried to not limit it unknowingly.

Based on you comment I assume, it would be sufficient to pass either signinRedirect or signinPopup as options to the hook.

Update: I adjusted the pull request to only allow signinRedirect and signinPopup as options.

Lets use the same name/type for error as already used in useAuth: error?: Error;

[aBytex]

Sure, I changed it to return the error as in useAuth instead and thus adapted the type to Pick return types from the already defined AuthState interface.

Please check if you are happy with that🙂

looks good, there is one last small thing remaining (see above)
