If you use Palm OS and have personal information the needs to be secure then check out Secure It by Brian Schau. It functions like the memo application, but is password protected. The ability to create teamplates is priceless, because it can reduce the amount of writing. I currently have 4 different templates: Auto, Credit Card, Internet Account, Personal Information. It is so nice to be able to remeber one password.

The templates that I use:
Auto
Make:
Year:
Model:
Engine:
License:
VIN:

Credit Card
Card no#:
Expiry date:
Name as printed:
Security Code:

Internet Account
Hostname:
Username: chadsmiley
Password: your normal password

Personal Information
SSN:
Date of Birth:

There are more features like export and import. Check out the Secure It Manual for all the features, with screen shots.
