The most obvious change in 1Password 4.5 is a completely redesigned user interface that brings the app in line with iOS 7’s look and feel.
Once you’re a 1Password user, the built-in browser rapidly becomes your most-used app feature, since the alternative would be to painstakingly (and painfully) copy your usernames and passwords into your browser.
Changes aside, 1Password is, and remains, a mature app that does its job remarkably well.
