Selznick Scientific Software has announced PasswordWallet 2.0, which is Carbonized to run in Mac OS X.

The application is a secure, easy-to-use repository for user names, passwords, PIN numbers and combinations, according to the company. It's also capable of saving Web addresses with their relevant codes, and will launch default browsers on request.

The information is kept secure because PasswordWallet uses the BlowFish encryption algorithm with 448-bit keys to protect data. In Mac OS 9 or later, the application will add the "master" password - used to access all other passwords - to the Keychain Control Panel. PasswordWallet will work on Mac OS 8.1 or later.

New features in version 2.0 include the ability to synchronize with Palm-compatible PDAs - in conjunction with PasswordWallet for Palm OS. The revised version of the application also has a built-in random password generator and can copy-&-paste passwords between files.

The application costs $15 and is available for download from Selznick Scientific Software. PasswordWallet for Palm OS costs $12.
