So far I’ve found two fairly good, free, password managers for OS X.
1. Pastor – Does the job, not very customizable (read: not customizable at all). Pastor allows you to easily use several databases for different categories of passwords.
2. Chilisafe – Chilisafe allows you to have categories with four customizable fields. It’s currently free, but I’m not counting on it staying that way. Of the two, Chilisafe is definitely more powerful. It even has a built in password generator and great search capabilities.
[update 10/18/04 – added The Vault]
3. The Vault – This is a freeform secure information storage solution. I like how you’re not restricted to the fields that come by default with most password managers. You get full text formatting options and from my quick tests there aren’t any arbitrary limits on the amount of text in the field. Categories might be nice, but for what it does, and the price (free) it’s not bad at all.
