"Active Directory - Password" login in SSMS for Azure AD - Password expired
When you reset a password in Azure AD, it automatically forces the user to change the PW on the next login.  If you immediately attempt to login to Azure SQL it will give you an error that the PW is expired.  


Log into the Azure Portal as sqladmin@myuserhotmail.onmicrosoft.com, set a new password and this will resolve your issue.
