Delta Drive, Delta Trust & My Drive · Security, sign-in and privacy
How do I turn on two-step sign-in for Delta Drive?
Short answer: In Delta Drive on the web, open Security → Set it up, add it to an authenticator app and enter a working code. Then sign-in needs your email code plus the app's code. Save the recovery codes — they're shown once.
In a browser, sign in to Delta Drive and open Security in the sidebar, then choose Set it up. Add the account to an authenticator app on your phone, then type a working code to prove it.
Nothing is enforced until you've typed a working code — so you can't lock yourself out with an app that never worked. Once it's on, signing in needs your email code and a code from the app.
You'll be shown a set of recovery codes exactly once. Each works once and they're your way in if you lose your phone, so print them or keep them somewhere that isn't that phone. See lost your phone?
