There are two methodsofencryption which can be used: the Android KeyStore or a Password/PIN. The KeyStore is a system component of Android forsecurelystoring cryptographic keys, the advantage of this approachis thatthe key is kept separate from the apps data and, as a bonus,can bebacked by hardware cryptography (if your device supportsthis).However, due to that separation, backups with 3rd-party appslikeTitanium Backup can not be used if this method is chosen. Suchappsonly backup the encrypted data files and not the encryptionkey,which renders them useless. In this case you will have to relyonthe internal backup functions provided by andOTP! The KeyStoreisknown to cause a lot of problems, so please only use it ifyouabsolutely have to and know what you are doing. In that casepleasemake sure to make regular backups in case something goeswrong. Itis always recommended to use a password or PIN instead!Betatesting: If you found a bug during beta testing, please submityourfeedback directly onGithub(https://github.com/andOTP/andOTP/issues) because for somereason Idon't always get notified when new beta feedback issubmitted onthe Google Play Store.
