Microsoft Authenticator Setup


The Microsoft Authenticator app helps you sign in to your accounts when you're using two-factor verification. Two-factor verification helps you to use your accounts more securely because passwords can be forgotten, stolen, or compromised. As a code generator for any other accounts that support authenticator apps.

Authenticator works with any account that uses two-factor verification and supports the time-based one-time password (TOTP) standards.

Your organization might require you to use the Authenticator app to sign in and access your organization's data and documents, both in the office and via VPN.
