About this Tool
![]()
iOS two-factor authenticator that generates TOTP codes for securing online accounts — works offline, no account required.
The app allows users to scan QR codes or enter setup keys manually to add accounts, then generates rotating 6- or 8-digit codes that expire every 30 seconds. Codes are generated entirely on-device, meaning no internet connection is required once an account is added.
Designed for simplicity, the app keeps authentication fast and low-friction without requiring an account or cloud sync. It is suited for individuals who want a lightweight, offline-capable authenticator without additional complexity.
