2FA Authenticator generates time-based one-time codes for accounts that support standard TOTP two-factor authentication.
CURRENT AND NEXT CODES
See your current code and the next code together. Tap either code to copy it independently. Each account uses its own configured code length, algorithm and time period.
ADD AND MANAGE ACCOUNTS
Add a setup key manually, scan a supported TOTP QR code with the camera, or import one from an image. QR images are decoded on your device and discarded. Rename accounts later, search your accounts, and keep their original imported setup link for recovery. Manual settings support SHA1, SHA256 and SHA512, six or eight digits, and custom time periods.
ARCHIVE AND HISTORY
Archive accounts and restore them whenever you need them again. Inspect each account's creation, update, archive and restore history. Permanent deletion is available for archived accounts and requires explicit agreement and the complete current setup key.
OFFLINE AND FREE
Core code generation works offline. No Noler account, ads, subscription or in-app purchase is required.
Keep your device time accurate. Setup keys remain visible and are stored locally without an additional app-level vault password or encryption layer. Protect access to your device and its backups. A next code becomes valid when the account's next time period begins.
Offline TOTP codes, QR import, next-code copying and account history.
