Either approve the notification sent to the Microsoft Authenticator, or enter the one-time password (OTP) generated by the app. The one-time passwords (OTP codes) have a 30 second timer counting down. When logging in with multi-factor authentication, you’ll enter your password, and then you’ll be asked for an additional way to prove it’s really you.
