AgileBits explains what the 1Password extension for iOS 8 will be capable of:

1. Access their 1Password Logins to automatically fill your login page.
2. Use the Strong Password Generator to create unique passwords during registration, and save the new Login within 1Password.
3. Quickly fill 1Password Logins directly into web views.

If you’re a developer working on an iOS 8 app that includes user registrations and logins, I strongly recommend considering the upcoming 1Password extension. The integration with the OS and the main 1Password app is incredible, especially if you’re used to the limitations of iOS and the things you’re not supposed to have on an iPhone or iPad.

The fact that the extension will also offer a password generator is a solid incentive to implement it – you’ll give 1Password users a way to easily retrieve and create secure passwords within the context of your app. This is one of the most exciting changes coming with iOS 8 (and there will be many).
