How-To

We recommend using the FREE Microsoft Authenticator app to receive notifications on your smartphone or tablet to verify your identity when prompted for M365 Multi-Factor Authentication (MFA).  Many users will find this the most convenient method for MFA, as many applications now allow the option to take advantage of built-in biometrics software (Face recognition or finger print), available on some devices, to assist with secure log in.
