Dan Moren, in his preview of 1Password 4 for Mac:

Several of the newest capabilities originated in 1Password 4 for iOS, including the ability to mark your frequently used items as Favorites, support for multiple logins on the same site, and the ability to sync via iCloud. You’ll also find new types of items to supplement existing options, such as driver licenses and reward programs, and you can add custom fields to most items, to store any other information you want. And if you want to share a specific item between the Mac and iOS apps, you can do so by sending it via encrypted iMessage or email.

1Password for Mac received its last big update in 2009 with version 3, and, following the launch of 1Password 4 for iOS, a revamp of the desktop client is long overdue. I’m particularly excited about the Back to the Mac approach – 1Password 4 is one of my favorite and most used iOS apps, and the upcoming Mac app seems to retain much of the mobile counterpart’s functionality, enhancing it with features that make sense on OS X (such as the new browser extension).

Apple will provide its own password generation and sync solution with iCloud Keychain, and that’s great news because it’ll help users have safer logins with minimal effort. However, I want more from my password manager, and I’m looking forward to trying 1Password 4.0.
