[!INCLUDEtsql-appliesto-ss2008-asdb-xxxx-pdw-md]
Returns one row for every [!INCLUDEssNoVersion] authentication login.
| Column name | Data type | Description |
|---|---|---|
| <inherited columns> | -- | Inherits from sys.server_principals. |
| is_policy_checked | bit | Password policy is checked. |

For a list of columns that this view inherits, see sys.server_principals (Transact-SQL). The columns owning_principal_id and is_fixed_role is not inherited from sys.server_principals.
To view both [!INCLUDEssNoVersion] authentication logins and Windows authentication logins, see sys.server_principals (Transact-SQL).
When contained database users are enabled, connections can be made without logins. To identify those accounts, see sys.database_principals (Transact-SQL).
SQL Server: Any [!INCLUDEssNoVersion] authentication login can see their own login name, and the sa login. To see other logins, requires ALTER ANY LOGIN, or a permission on the login.
To view the contents of the password_hash column, the CONTROL SERVER permission is required.
Azure SQL Database: only members of the special database role loginmanager in master or the AAD Admin and Server Admin can see all logins.
[!INCLUDEssCatViewPerm] For more information, see Metadata Visibility Configuration.
