Google Authenticator – manual backup and restore

If we have ROOT access we can manualy backup the file that contains seeds needed to generate password in application.

Backup: You need to set ROOT access for ADB, and then:

adb pull /data/data/com.google.android.apps.authenticator2/databases/databases

The content of the file can be display with help of sqlite client application:

sqlite3 ./databases

select * from accounts;

The above method can be done with file manager that can get ROOT access

Restore backup: You need to set ROOT access for ADB, and then:

adb push databases /data/data/com.google.android.apps.authenticator2/databases/databases
adb shell
#here we need to know which user and group we need to use
chown user:group /data/data/com.google.android.apps.authenticator2/databases/databases

The above method can be done with file manager that can get ROOT access and copy databases file to:

/data/data/com.google.android.apps.authenticator2/databases/databases

Also remember to set ownership for proper application user (com.google.android.apps.authenticator2) on this file, because with wrong one (root) the application will crash every time you try to open it.
