Uwagi

sp_password calls ALTER LOGIN. This statement supports additional options. For information on changing passwords, see ALTER LOGIN (Transact-SQL).

sp_password cannot be executed within a user-defined transaction.

Permissions

Requires ALTER ANY LOGIN permission. Also requires CONTROL SERVER permission to reset a password without supplying the old password, or if the login that is being changed has CONTROL SERVER permission.

A principal can change its own password.

Examples

A. Changing the password of a login without knowing the old password

The following example shows how to use ALTER LOGIN to change the password for the login Victoria to B3r1000d#2-36. This is the preferred method. The user that is executing this command must have CONTROL SERVER permission.

ALTER LOGIN Victoria WITH PASSWORD = 'B3r1000d#2-36';
GO

B. Changing a password

The following example shows how to use ALTER LOGIN to change the password for the login Victoria from B3r1000d#2-36 to V1cteAmanti55imE. This is the preferred method. User Victoria can execute this command without additional permissions. Other users require ALTER ANY LOGIN permission.

ALTER LOGIN Victoria WITH 
     PASSWORD = 'V1cteAmanti55imE' 
     OLD_PASSWORD = 'B3r1000d#2-36';
