You can use a recovery code to access your enterprise account when a authentication configuration error or an issue with your identity provider (IdP) prevents you from using SSO.
In order to access your enterprise account this way, you must have previously downloaded and stored the recovery codes for your enterprise. For more information, see "Downloading your enterprise account's single sign-on recovery codes."
You can only use recovery codes once and you must use your codes in consecutive order. Recovery codes grant access for 24 hours.
Note: If your enterprises uses Enterprise Managed Users, you must sign in as the setup user to use a recovery code.
At the bottom of the single sign-on dialog, click Use a recovery code to bypass single sign-on.
In the "Recovery Code" field, type your recovery code.
After you've used a recovery code, make sure to note that the code is no longer valid. You will not be able to reuse the recovery code.
