Fear me, for I am root

Google Authenticator Plugin: I’m sorry, but it is not possible for you to import an existing shared secret. You must generate a new one.

Me: Really? That’s annoying.

GAP: Yup. Sucks to be you.

Me: Fine. *generates a new secret* Oh, there’s something I ought to tell you.

GAP: Tell me.

Me: I have root access to the database in which the secret is stored. *edits the appropriate entry in the database, thus restoring the previous shared secret*
