I assign all of my SQL Server logins to the tempdb as the default database. NEVER master. This way no harm can be done by an application that just connects to the server without specifying a database name as part of the connection string. Ideally, I'd like to see an option of "none".
I second this, I really wish that we could set this as a default so when someone creates a new user it would be already entered.
