Hi @CarolWadsworth,

If you're a Canvas administrator, you should be able to change a user's password following the  How do I manage a user's login information in an a... - Instructure Community  guide (see the "update login" section) IF you use build-in Canvas authentication.  If you use a third party SSO solution for login, you'd need to follow whatever directions you have for that login provider.

Hope this helps a bit!
