Ratings and reviews

This app is extremely basic and lacks features that other TOTP apps have. It's inconvenient for managing a large number of accounts: since they're just one flat list that can't be searched or sorted, you have to scroll through the entire thing in search of the one you need. Exporting just one account also requires you to manually unselect all the other accounts one by one. Accounts can't be renamed (only the username can be changed) and you can't set custom icons for them. The app can't be protected by a pin or biometrics. On the plus side, the QR code scanner is incredibly fast.

Since the last update, the app crashes immediately upon opening, rendering it useless. And judging by other reviews, I'm far from the only one with this issue. Reliability is a must for a security-app and it has failed spectacularly. [EDIT] A few days later, an update has fixed the issue. Increasing my rating, but only to 3* as such basic problems shouldn't happen with such a simple app.

It needs PIN and fingerprint protection. Also, a backup function in case you lose your phone. At least an offline backup which you can move somewhere secure. Also, a "thrash" folder where to move deleted keys, just in case you make the mistake of deleting them without wanting out realising that you still need them. Do this and you'll become one the best apps.
