Description

Auth is a 2-factor authentication app that generates time-based one time passwords (TOTP).

Simply tap on the generated code to copy it to your clipboard. Using iCloud shared clipboard you can paste the code on any of your devices.

By enabling iCloud Sync your accounts are shared between all of your devices, allowing you to generate your authentication code on any of your devices.

In settings you can enable AutoFill to automatically fill your verification codes from the Auth App. Note that this may require editing your existing codes to set the autofill websites - popular providers are auto-recognised and configured as far as possible.

Features include:
- iCloud Support
- AutoFill
- Supports iOS Dark Theme
- Works with all the most popular websites
- TOTP QR code recognition from the camera app or from photos
