User Reviews

Reviews praise the app for being simple, ad-free, privacy-focused, and compatible with older devices. The most mentioned drawbacks are lack of easy token migration to new devices, no cloud backups, and stability issues after OS updates, plus missing security features like biometrics or passcodes.

Pros

Simple setup and easy to add accounts
Ad-free and lightweight user experience
Privacy-focused with no data collection and open-source
Good backward compatibility with older iPhones/devices
Clear, minimal design that focuses on core 2FA functionality

Cons

Inability to transfer/export tokens to a new device, risking data loss when upgrading
No cloud backup or account-based restore; relies on device storage only
Stability issues after OS updates (e.g., blank screens, codes not generating)
No ability to switch devices or migrate between devices easily
Lack of biometric/PIN protection and no Apple Watch support

That’s a major issue , i can’t log in to my account because that code was not showing and app can’t run

Been using this app for 2FA for years. Upgraded my phone to IOS 26 due to security updates no longer being available for IOS 18 and it turns out this app no longer works on IOS 26. It just shows a blank screen. I lost all my tokens which sucks.
