About this app

AuthGuard 2FA is a private, offline two-factor authentication (2FA/MFA) app. It generates time-based one-time passwords (TOTP/OTP) for your accounts, stores them encrypted on your device and never asks you to sign up.

Private by design
• No account, no sign-up, no cloud
• No ads, no tracking, no analytics
• Codes are generated fully offline
• Your secrets stay on your device; backups are encrypted and made only when you choose

Strong encryption
• Secrets encrypted with AES-256-GCM
• Keys protected by the Android Keystore (hardware-backed where available)
• Password-protected encrypted backups

Easy to set up
• Scan a QR code or type the setup key manually
• Tap a code to copy it
• Live countdown shows when each code refreshes
• Clean frosted-glass design
• Available in 36 languages

Backup and restore
• Export an encrypted backup file that you control
• Restore it on a new phone with your backup password
• Merge with existing accounts or replace them

Works with your accounts
Works with any website or service that offers 2-step verification with an authenticator app (standard TOTP codes and otpauth QR codes).

Technical details
• TOTP, RFC 6238
• SHA-1, SHA-256 and SHA-512
