It is not possible to recover data from backup files created by a third-party application. For security measures, the 2FAS local database is encrypted with a random key generated during app installation (each app installation has a different key). This key is securely stored in the system keystore and cannot be accessed outside the scope of the 2FAS app. That's why we offer other backup methods - manual or automatic through Google Drive.

I don't know what to do now. I even cloned the source code of the 2fas-android project and opened it with Android Studio. I found the code related to 'import from file', but I still don't know how to import my backup data:

database-2fas-shm, database-2fas-wal, and database-2fas.

"Import from file" option is for backup files created using our in-app solution in "Settings -> 2FAS Backup -> Export to file".

Those database files are encrypted and it's impossible to import them. It's done for security measures.

Yeah, Android backup is completely useless for this kind of apps.
