Thank you for this recommendation. Just tried Aegis on Android:
1. Its UX is more polished than andOTP; the AMOLED theme in particular is well done.
2. It also supports fingerprint unlocking, the lack of which was the biggest pain point when regularly using andOTP.
3. Supports imports from popular 2FA apps, though this requires root access.
A few issues I noticed:
1. While importing from andOTP, the issuer is blank when the 2FA token was manually added to andOTP. So now I have a list of 2FA codes with no indication as to which website they belong to. [Screenshot](https://gopi.dev/images/aegis.jpg)
2. The 'Vault is unlocked' notification persists even on closing the app.
3. OpenPGP integration for backups isn't available.
