Password keeper help.

About a month ago I saw an article about a pager sized device that stores and generates passwords. I have about 20 passwords I use at work and now big giant airplane company has decided everyone needs to change their passwords every 60 days. They say it is for security. Does anybody have any idea what I am talking about. I have tried searching the web without any success. I think I could use a device like this. Password generators stored on computers won’t be any help. In my typical work day, I have access to over 100 computers and probably use a quarter of them. Something I could carry with me would be a big help.

I don’t know about the device you speak (type) of but the palm has programs for storing passwords and that program is (you guessed it) password protected - don’t remember what it is but you should be able to find it
