Is it possible to have the same Role available as SSO and direct login with email and password? I have been looking for information about it, but it is not clear to me. Thank you

No it’s not possible

There is a workaround - create a copy of the role in question - remove SAML permission and save with a different name. Assign both the roles (SAML and Non-SAML role) to the users. Now they should be able to login via both method. Note that if you have workflow or scripts where this role is referenced make sure to add the new role too

That's what I have been doing, but I was trying to figure out something different easier to maintain. Thanks a lot for sharing.
