Great news for you out there!
For those of you looking to implement Single Sign On. We have recently updated our Single Sign on so natively out of the setup your directly will be setup as a SHA-256 setup so you can do the setup directly from the Admin console rather than reaching out to Client Care teams.
We will have a migration option for you coming soon! For upgrades for Single Sign on please reach out to Client care teams to be assisted for current integration setups that need Cert renewals.
If you have questions please let me know!
