Hi Jason,
SQL Server does not provide such function. You may give Microsoft

Personally I do not think that this is a secure way since your valid

function in your application level by yourself. I think that your meaning
of locking logins here is that you temporarily DENY all the permissions

If you have any other questions or concerns, please feel free to let me
know. Have a good day!
