Password change not available because created with Google

I am trying to change my password so I can log on to Slido on a different computer. It is telling me “If you created your account with Google or SAML SSO, the option to change your password will not be available to you.” I cannot find a way to change this. Do I need to create a new Slido account and start over? The Slido account is on my personal Mac, I want to use it on a powerpoint on a work PC. Thank you
