1Passwd is a unique password manager that integrates directly within your web browser. This allows you to access your web passwords when you need them without ever needing to switch applications, and never needing to copy-n-paste! 1Passwd runs on Macs.
The new beta 2.5 version of 1Passwd has added a “Sync to iPhone” feature which will export all your 1Password data to an encrypted Safari Bookmarklet, which can then be used on the iPhone (or iPod Touch) to access all your information. Everything is encrypted with 448-bit Blowfish with Cipher Block Chaining (CBC) and randomized salt. After syncing you will see the new bookmark in Safari. Tapping the bookmark will open a page asking for your Access Code. If the password was correct, you will be shown your standard 1Password sections. In a few days you can download the official 2.5 version via automatic updates in 1Passwd.
This software is for Mac Users only. The full version costs $29.95.
