Best Practices for Passwords

Is there a "Best Practices" guide on setting passwords for HandHelds?

When we create accounts for users, we can either do it one at a time via
ConsoleOne or bulkload, and we usually put in the same temporary
first-time password. This gets them into their PC, portal, etc.

How would this work for HandHelds? I'd like to do the same thing. Who
has done this, what does it take to do, and what do you recommend?

Thanks!
