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

Recent reviews

This is a great app that does nothing at all except display 2fa codes. All apps try to do everything. It is refreshing to see an app that does as little as possible. A side effect of this is that it is not clear how to export the codes. Can the developer reply to this or email me and let me know? I can handle complicated solutions like decrypting and dissecting a full phone backup if this is the only way. (but plz lmk where to get what)
