Hi,
I have forgotten which authentication app to be used for logging in? How do I generate recovery codes? so please tell me which authenticator app is being used in infinityfee.com? And where is the settings for that in this site?
I have only 8 recovery codes saved in a notepad but it is saying that only onetime it can be used. so what to do during login when all my recovery codes have been used one times?
Recovery codes need to be generated while you are logged into your account. You can use any authenticator that supports basic OTP auth, popular choices include Authy, Microsoft Authenticator, etc.
Recovery codes should never be used unless you lose your OTP device, you should be using your OTP device (The device you scanned the QR code with / entered the secret phrase into when you setup 2FA)
