STROB  In the past year I upgraded to v4 to sync with my palm. But this version has been plagued with duplication of entries during the sync process that is very frustrating. Splashdata support has been virtually non-existant these days. Posts to their forums and emails to their technical support go unanswered. In my eyes Splashdata had been one of the best developers for the Palm with Mac destop support. Now I am looking for another password manager to replace it. Very sad.

AKROBAT  I agree with the post below, plus the fact that this software has not been updated in 3 years. Reminds me of Palm Desktop...   
(Version 3.32)

SJK  Reliable and stable; flawless synchronization with a few different Palm models over several years. I disagree with the previous "great interface" comment since the desktop UI is sadly underdeveloped for OS X. A couple examples:

* No support for changing multiple entries at once (e.g. categories or masking fields).

* Uses several non-standard shortcuts (e.g. command-M for Mask/Unmask instead of Minimize).

FDQN4FH  Good program. Great interface. Works even as a standalone (without the Palm synchronisation). I have 600+ entries: no stability problems. Could be faster on a Macintel: unfortunately no Universal Binary planned.

LISA  I've used this software for a few years and really like it alot - have it installed on all my computers. Invaluable for quickly retrieving credit card data, passwords, etc. Couldn't live without it!

MACNAB  Simple - does the job.

I use it all the time
