# What if I lose the phone with my Delta Drive authenticator app?

Use one of the **recovery codes** you were shown when you turned two-step sign-in on. Each one works once, in place of the authenticator code.

We can't show those codes again — we keep only a fingerprint of them, so it isn't something we're able to do rather than something we decline to do. The Security screen tells you how many recovery codes you have left; when you're down to the last couple, turn two-step sign-in off and on again to get a fresh set.
