I have a rooted Nexus 5 running stock 4.4.2. I want to install another ROM such as PA4 or CM11 (also 4.4.x based), but I have about 5-odd items in my Google Authenticator install which are a pain to configure all over again on the 'new' device. Will using Titanium Backup to backup and restore Google Authenticator preserve the settings and tokens?

I read somewhere that it doesn't work if you move between major versions of the OS and even though I'm moving from 4.4 to 4.4, I am changing the base ROM, so I'm not so sure.

If anyone has tried this and hasn't been able to move GA over gracefully, I might just stick around with the stock ROM for a little while longer, because I only just got this phone a couple weeks ago.

  • I don't know the answer, but: You might consider taking a Nandroid backup before you flash the new ROM (which you should do anyway). So in case it does not work out, you at least can revert easily to the previous ROM by restoring the Nandroid backup, and "continue where you left". – Izzy Dec 26 '13 at 15:38
  • Nandroid... Now that's a name I've not heard in a long, long time! – aalaap Feb 2 '14 at 3:26
  • It's even mentioned in our fine backup tag-wiki. Also has its own fine tag-wiki. Just in case :) – Izzy Feb 2 '14 at 12:27

It worked fine for me.

I recently replaced my Sony Xperia Z with a Nexus 5. I copied over the Titanium Backup files and restored them, including Google Authenticator. No problems to report, I can still connect correctly to sites and apps requiring a code.

  • This is very promising! – aalaap Feb 2 '14 at 3:24
