Hi there!

Is there any way to use base32 encoded secret got from otpauth://totp/smth?secret=xxxxxxx&issuer=zzz URL Tried to paste it in config. App runs smoothly but generated codes are wrong.

Hey, what you need to take out of such a URIs is whatever is going after secret= and till & or end of string.

So in your example otpauth://totp/smth?secret=xxxxxxx&issuer=zzz what you need to provide to Flipper Authenticator is xxxxxxx only.

Thanks for your reply. Yeah that's exactly what i've done. Also I checked that flipper clock is synced through BT with flipper app. Trying to login into my Github profile for example. I'm using SHA-1. Still doesn't work.

I wonder if codes generated with flipper must exactly match with Google Authenticator codes?

Have you set correct timezone offset in Flipper Authenticator?

ilyabreev commented 1 year ago

Yes. It's MSK for my case (+3h).

Forgot to mention that flipper-zero authenticator refreshes codes slightly later than Google Authenticator app (with 0.5-1.5 seconds delay). May be this an issue?
