Password

I have always taught people that your password should be kept secure from everyone, no matter how close they are, UNLESS you have good reason to tell them. The main good reasons are: 1) The person has to make changes to your machine 2) You want someone - trusted of course - to read your emails, &c. while you are away 3) You become too ill to use the account 4) You die In the first and second cases, it's a good idea to change your password after the need has expired (sometimes I recommend changing it before and after). It isn't a matter of 'privacy': it's a matter of security. Nor is it a matter of 'lack of trust': it's just a protocol which everyone should abide by and expect of others. I actually find it quite embarrassing when someone blithely tells me their password for something and I always instruct them to change it as soon as possible. It doesn't matter whether I am the IT guy who they can trust or what - passwords are as sacred as the name of God!
