Authenticator: 2FA & MFA

Authenticator is a privacy-first 2FA / MFA authenticator app for Android. Generate secure TOTP one-time passwords offline, keep accounts organized, and store passwords in one encrypted vault — with optional end-to-end encrypted backup when you go Premium.

WHY PEOPLE CHOOSE AUTHENTICATOR

TWO-FACTOR AUTHENTICATION THAT STAYS ON YOUR DEVICE
