Hi @Ravi Kiran Palivela ,
The reason for the login is so that people don't bookmark the profile edit page and then sign out. So you need to make this work via SSO so that the Profile Edit will skip the sign-in step after you have used the sign-in journey.
If you copy the profile edit page from the Azure portal and remove the prompt=login parameter, you'll be taken straight to the Profile Edit page and bypass the IdP selection, rather than seeing the sign in page. You can test this by completing the sign-in journey, ppening a new tab, copying the profile edit link but removing prompt=login, and signing in.
