Recovering Google Authenticator keys from Android device for backup
### 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:me@gmail.com|XXXXXXXXXXXXXXXXXXXXXXXX|0|0|0||
2|Google:me@domain.org|XXXXXXXXXXXXXXXXXXXXXXXX|0|0|0|Google|Google:me@domain.org
3|Dropbox:me@gmail.com|XXXXXXXXXXXXXXXXXXXXXXXX|0|0|0|Dropbox|Dropbox:me@gmail.com
### 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.
