If you are experiencing an error when trying to log into Honeycomb with SSO, you may already have an existing Honeycomb account that uses e-mail address and password as login credentials. 

To convert a pre-existing Honeycomb account to SSO, you must authenticate with your Honeycomb account credentials before attempting to use SSO sign-in. Please see our documentation:

If you continue to have SSO issues, please do file a Support ticket and we'll take a look!
