A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Hi Chey,
It sounds like you are stuck in a sign-in loop because Microsoft Authenticator is the only verification method available. For a work account, your IT administrator can reset your MFA registration so you can sign in and set up Authenticator again. Microsoft also recommends using another available sign-in method if one is listed.
Thank you, Chey, and feel free to respond back for more assistance.
