I will be happy to use Microsoft Authenticator. I have a lot of address for many websites and everything is synch and yes it works much better than rest, even better than google.
Don't know why Microsoft Authenticator is still not available for Firefox. This is the only reason I don't use Firefox. Microsoft Authenticator can be used as a password manager for mobile phones and PC.
I can not use Microsoft authenticator with a new account of my friend. What changed? I used it before many years. You can tell me, that i can not login with my account?
