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
• Offline 2FA codes — works without internet, Wi‑Fi, or mobile data

TWO-FACTOR AUTHENTICATION THAT STAYS ON YOUR DEVICE
Protect email, work, banking, crypto, social, and other accounts with time-based one-time passwords (TOTP / OTP). Codes refresh automatically so you always have a fresh verification code ready. Prefer authenticator app 2FA over SMS to reduce SIM-swap risk.
