To view both SQL Server 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).

Any SQL Server 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.

The visibility of the metadata in catalog views is limited to securables that a user either owns or on which the user has been granted some permission. For more information, see Metadata Visibility Configuration.
