The more I use ssh, the more I like it, but the more I find I don't
understand.  So today I got rsa authorization to work, and realized
I don't need a password anymore (this particular user never logs
in via the console, only remotely via ssh).  I did vipw as root and
replaced the password string with '*' as it seemed like it would make
things only that more secure for users like that.

Question1: will that cause trouble in some unforeseen way?  Question2:
is there a "better" or more "standard" way of blocking logins with a plain
password?  TIA
