What they are
When MFA turns on, you get 10 recovery codes, like abcde-fghij. Each one
signs you in once, in place of a code from your app. They're shown only
once: select Download or Print, and keep them away from your phone.
Sign in with a recovery code
- After your password, select Use a recovery code instead.
- Enter one code and select Verify.
- On the You signed in with a recovery code page, select Generate new recovery codes and save the new set.
Lost your phone
- Sign in with a recovery code.
- On the You signed in with a recovery code page, select Generate new recovery codes and save them.
- On the MFA page, select Remove next to the lost phone, then add your new one.
No codes left? Ask a staff member to reset your MFA.
New codes
The MFA page shows how many codes are unused. On that page, Generate new codes gives you a fresh set; your old codes stop working.
