Vaultly Authenticator is an offline authenticator app that generates your two-factor authentication (2FA) codes right on your phone, even when you are offline. Scan a QR code, copy your one-time password with a single tap and sign in. No Vaultly account, no sign-up, no ads.

ADD ACCOUNTS IN SECONDS
• Scan the QR code a website shows when you turn on two-factor authentication
• Import a QR code from a screenshot or image
• Open or paste an otpauth:// link
• Enter the setup key manually
Vaultly works with services that support standard authenticator apps for two-step verification (TOTP and HOTP).

CODES THAT WORK OFFLINE
As a TOTP authenticator, Vaultly generates time-based (TOTP) and counter-based (HOTP) one-time passwords on your device without an internet connection. When a service requires it, choose 6 or 8 digits, a 30 or 60 second period and SHA-1, SHA-256 or SHA-512.

FIND THE RIGHT CODE FAST
• One-tap copy with a clear countdown
• Copied codes are cleared from the clipboard automatically
• Search by service or account name
• Favorites, categories and custom sorting
• Code history for every account
• Optional auto-minimize on Android after you copy a code

PROTECT ACCESS TO YOUR CODES
• 6-digit app PIN
• Fingerprint or face unlock on supported devices
• Lock when you leave the app
• One-time recovery codes if you forget your PIN

AUTHENTICATOR BACKUP AND NEW PHONE TRANSFER
• Encrypted authenticator backup files (.vaultly) protected by their own backup key
• Google Drive backup, encrypted on your device before upload
• Move to a new phone using your encrypted backup
• Import plain JSON exports from Vaultly, 2FAS and Aegis
JSON exports are not encrypted and contain your account secrets, so store them carefully. Vaultly does not keep your authenticator accounts, backups or recovery keys on its own servers.
