| ### Last tested February 7 2014 on a Galaxy S3 (d2att) running Cyanogenmod 11 nightly, with Google Authenticator 2.49. | |
| ### Device with Google Authenticator must have root. | |
| ### Computer requires Android Developer Tools and SQLite 3. | |
| ### Connect your device in USB debugging mode. | |
| $ cd /tmp | |
| $ adb root | |
| $ adb pull /data/data/com.google.android.apps.authenticator2/databases/databases | |
| $ sqlite3 ./databases "select * from accounts" > /Volumes/TRUECRYPT_ENCRYPTED_VOLUME/google_authenticator_backup.txt | |
| $ rm ./databases | |
| ### If you look at the file, you see a pipe-delimited file with entries looking like the following. | |
| ### The X's mark the key. | |
| 1|Google:[email protected]|XXXXXXXXXXXXXXXXXXXXXXXX|0|0|0|| | |
| 2|Google:[email protected]|XXXXXXXXXXXXXXXXXXXXXXXX|0|0|0|Google|Google:[email protected] | |
| 3|Dropbox:[email protected]|XXXXXXXXXXXXXXXXXXXXXXXX|0|0|0|Dropbox|Dropbox:[email protected] | |
| ### To restore the keys, you can key them in manually in Google Authenticator: | |
| ### Menu -> Set up account -> Enter provided key. | |
| ### Enter the key exactly as it appears, case sensitive, and choose Time-based. |
I searched Google and accidentally found this website that can decode secrets from the newer Apps. I tested myself and it did work.
It requires the QR codes, so it doesn't decrypt them "just by the database file".
You can try disabling selinux. Tried the earlier suggestions, but Authenticator kept crashing. Restoring through Titanium backup that way, while upgrading from Android 10 to Android 13, I managed to recover my passwords.
