I assume you mean that creating the logins with a new password isn't OK?

First, that's horrible security. If you can't change a password, you are asking to be hacked, and your organization deserves to suffer penalties for this. Security 101 is that I have to be able to change a password if something is compromised. I'd use this as an opportunity to fix that.

However, the  HASHED option from  CREATE LOGIN doesn't appear to work.  I've  queried others to see if there is another workaround. There are password brute force crackers out there that you might be able to use. What vesrion of SQL Server on premises?
