Microsoft Authenticator: Account Security

Microsoft Authenticator enhances your online security with multi-factor authentication (MFA), adding a crucial second layer of protection. After entering your password, approve a notification or use a one-time password (OTP) generated by the app. These OTP codes refresh every 30 seconds, ensuring you never reuse a code. Enjoy passwordless login by simply approving a notification on your phone using your fingerprint, face ID, or PIN. Access Outlook, OneDrive, and Office seamlessly after two-factor authentication (2FA). The app also autofills passwords, syncing them from Microsoft Edge and allowing imports from Chrome and other password managers. For work or school accounts, Microsoft Authenticator supports certificate-based authentication, verifying trusted devices for secure access to Microsoft apps and services. Add multiple accounts, including Facebook, Amazon, Dropbox, Google, LinkedIn, and GitHub, for comprehensive security.
