A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Hi @Stelios Papafilippou , two months is a really long time to be stuck on this, I can imagine how annoying that must be.
Can you tell us exactly what error you are seeing? Like does it say the code is wrong, or you just never get the notification at all? And is this a personal account or a work account? That makes a big difference.
One thing I would check first is the time on your phone. If it is not set to automatic, the codes often get rejected even when they look right. Try turning automatic time on, then generate a fresh code and try again.
If that does not help, on the sign-in page try "Sign in another way" and use SMS or email if you have that set up. That at least gets you in for now.
And if you can get in that way, you can remove Authenticator from your security settings and add it again fresh. Just do not remove it if it is your only way in and you are fully locked out, then you will need the account recovery page instead.
Let us know what the exact error says and whether it is Android or iPhone, then it will be easier to figure out what is actually going wrong.
