Authenticator is a secure, modern 2FA app that generates TOTP and OTP codes for all your accounts. Protect your online identity with multi-factor authentication, encrypted backups, and instant QR code scanning.

SECURE TWO-FACTOR AUTHENTICATION
Add an extra layer of security to your online accounts. Authenticator generates time-based (TOTP) and counter-based (HOTP) one-time passwords that refresh automatically. Supports SHA-1, SHA-256, and SHA-512 algorithms with customizable code lengths and refresh intervals.

EASY SETUP — SCAN & GO
Point your camera at any QR code to add an account in seconds. Switching from another app? Import all your accounts at once with batch QR code migration. You can also add accounts manually if you prefer.

BUILT FOR PRIVACY & SECURITY
Your data stays yours. All account data is encrypted with AES-256 on your device. OTP secrets are stored separately in your device's secure enclave. Lock the app with Face ID, Touch ID, fingerprint, or a custom PIN. Auto-lock kicks in when you step away, and your clipboard clears automatically after 30 seconds.

ORGANIZE YOUR WAY
Group accounts into custom categories, pin your favorites to the top, and reorder with drag-and-drop. Find any account instantly with real-time search. Choose from 125+ service icons that are automatically matched to your accounts — or pick your own colors.

ENCRYPTED BACKUP & RESTORE
Never lose your codes. Create encrypted backup files protected by a master password that only you know. Restore your accounts on any device with your backup file and password. Your secrets are protected with AES-256-GCM encryption end-to-end.

HOME SCREEN WIDGETS
Access your most-used codes without opening the app. Pin up to 5 accounts to your home screen widget for one-glance verification. Codes refresh in real-time right on your home screen.

PREMIUM FEATURES
Upgrade to unlock home screen widgets, premium icon packs, encrypted cloud backup with cross-device sync, and priority access to new features.
