Ask any member of the TUAW team what they use to keep track of the swarm of passwords they are confronted with on a typical day, and they're likely to say 1Password. AgileBits today announced a major update to the iOS version of the app, which is available for free to current users. 1Password 4.5 will be on sale at half-price -- US$8.99 -- for those who don't already own it, through Friday, April 25.

What's new in the password manager? To start with, the app has a shiny new iOS 7 look and feel, complete with a new icon. But that's just the icing on the cake. Under that gooey frosting is:

  • A 34 percent smaller app footprint, saving 8.6 megabytes of space
  • Faster syncing
  • Search available all the time at the top of the Categories tab and each main category
  • AirDrop support for sharing items
  • Support for multiple vaults once they're configured in 1Password for Mac
  • A new Demo Vault replacing the venerable Demo Mode
  • A redesigned user setup process, as well as an improved upgrade process from 1Password 3 for iOS
  • Support for custom item images (must be added via 1Password 4 for Mac)
  • Tags added in Mac version sync with iOS
  • Improvements and bug fixes in Wi-Fi Sync
  • Support for multiple Dropbox accounts

Enhancements were made to the built-in 1Browser to allow for easier logins, faster checkouts, and online form auto-fill much in the way 1Password mini works on the Mac.

And speaking of the Mac, 1Password 4.3 for Mac was also released today with a variety of improvements.
