1Password 4 for Mac now available with new interface, 1Password mini, shared items, Wi-Fi sync, and more!

1Password 4 for Mac is now live and available. The popular OS X security application was updated this morning, and completely rewritten with a simple new interface and a host of new features. You can now set up multiple vaults that can be shared with family members or coworkers, and each vault gets their own sync preferences. You can even set up a demo vault to show off 1Password to others. Open the demo vault from the app's lock screen with the password "demo". Switch between vaults by tapping the keyhole icon next to 1Password's traffic lights. You can also share individual items.

1Password mini is now a full menubar utility. Access all of your login information, credit cards, folders, favorites, and the password generator right from your Mac's menubar. The new 1Password browser extension works the same way. Completely rewritten in Cocoa, the extension behaves the same across the Safari, Firefox, Chrome, and now Opera browsers.

The syncing capabilities of 1Password have also been expanded. In addition to Dropbox, Mac App Store customers can also use iCloud to sync with other Macs and iOS devices. Wi-Fi sync has also returned, giving you the option to move your data directly between devices, rather than rely on cloud storage.

1Password 4 for Mac is a free update to customers who purchased 1Password 3 from the Mac App Store (MAS). New customers will pay $39.99 right now as part of a launch sale, down 20% from the regular price of $49.99. Customers who purchased 1Password 3 from the AgileBits website in 2013 are also eligible for a free upgrade, while website customers who purchased in 2012 or earlier will get an upgrade price of $24.99, down from the regular price of $34.99. 1Password 4 will is currently only available on the Mac App Store, but will come to the AgileBits store very soon.

(If the upgrade pricing sounds complicated and lopsided, once again it's a great developer trying to do their best for as many customers as possible, while still trying to feed their families, given the incredible restrictions placed on App Store Pricing. Buy it. Don't buy it. Realize that if we don't support great indie software, people will stop being able to make it.)
