SQL Login

I have created one test login and give the access to one database, now when I have logged in from that id user has the option to change the password of SA via security tab, please suggest hot can I remove that tab

In SSMS object explorer, expand the Security -> Logins node, right click on the login, properties and in Server Roles uncheck permissions that you don't need. Typically you should grant only public role to a regular user, and then grant them permissions on specific databases and database objects that they need.
