AgileBits, the developers behind 1Password have unveiled app extension for third party apps. The extension will allow third-party developers to integrate 1Password access into their apps. That would allow 1Password users to fill in log-in information without ever leaving the other app. 
Prior to this on iOS, users had to copy and paste passwords out of password manager apps. AgileBits has also released a video preview that shows just how easy that extension will make it to use logins that are saved in 1Password on iOS devices. The company also plans to support TouchID for authentication. You press your thumb to Touch ID, and the extension automatically brings up the different accounts you have saved for that app. With another tap, the credentials are entered and you can sign in.

AgileBits has supplied documentation and sample code on GitHub for other developers wanting to integrate support for the app extension with other iOS 8 apps. 1Password made its debut on Android in June.
