This application has always been useful on iOS, but with the improved integration possible in iOS 8 (which AgileBits took full advantage of) it is really pleasant to use, especially if your device supports touch ID. I love the integration with safari, and the fact that searching for items is so easy.
Using a password vault is a really good idea, because it allows you to use very secure passwords that are different for every site, without the hassle of remembering or typing those long passwords. Of the password vaults I’ve tried on MacOS and iOS this one is by far the best. It is easy to use, well integrated with the operating system, has great support, very high security, and for the many years I’ve been using 1Password the company has offered affordable, worthwhile upgrades at sane intervals.
The new feature of being able to use touch ID after a restart is a neat idea, but I’m glad it can be turned off.
