We updated Bitly's navigation menu in September, 2022!
If you're used to the old look, check out the changes.
To login into your Bitly account with SSO, your Enterprise account will need to be set up with an identity provider. You'll then be able to log in using the login page created during step 5 of the set up process.
Check with the Bitly administrator in your organization if you're not sure of the login page address.
