How to revoke "Alter role" on users I have a user "sa" which is sysadmin in a MSSQL instance.
All users who log into the database have the permission to change the password and delete the "sa" user.
Is there a way to revoke this permission?
The only way other users have the ability to change the password of the SA account are other members of the sysdamin role and members of the security admin role. Are your users part of the sysadmin or security admin role?
