I would like to set up SSO for the Support Portal in the future, but as it takes a lot of development on our end and will take some time to add it to our roadmap.

I'd like to create profiles for some of my end users right now so they can start using the knowledge base.

If I do create profiles manually today and ask my client to log in manually, will I be able to set up the SSO for those same email credential in the future?
