Waterfall Software today announced the release of Wallet 2.0, a major update to its secure utility for storing passwords, serial numbers, contacts, and more. Wallet 2.0 has been “completely re-written from the ground up – increasing performance and security, as well as sporting an entirely new user interface.” Other new features in this release include: AutoFill, a feature which lets you automatically fill out internet-based forms in your favorite Web browser; and Quick Lock, a new feature that enables you to securely lock Wallet with one click. Version 2.0, which requires Mac OS X 10.3 or later, is available for US$14.95 for new users, and $5 for an upgrade for previous users of Wallet.
