To keep your account information as secure as possible CometOTP only stores it in encrypted data files. A part of the encryption key used for that is stored in the Android KeyStore system. The advantage of this approach is that the key is kept separate from the apps data and, as a bonus, can be backed by hardware cryptography (if your device supports this).
However, due to that separation, backups with 3rd-party apps like Titanium Backup can not be used with CometOTP. Such apps only backup the encrypted data files and not the encryption key, which renders them useless.
Please only use the internal backup functions provided by CometOTP to backup your accounts! Everything else WILL result in data loss.
- OpenPGP: OpenPGP can be used to easily decrypt the OpenPGP-encrypted backups on your PC.

">https://github.com/gigabytedevelopers/CometOTP/releases)-->Warning: All three versions (Google Play, F-Droid and the APKs) are not compatible (not signed by the same key)! You will have to uninstall one to install the other, which will delete all your data. So make sure you have a current backup before switching!
