With Screens for iOS, 1Password users can quickly access their stored passwords via the 1Password iOS extension.
1Password Toolbar Button
You can access all of your 1Password items directly from the Screens toolbar. Simply tap the 1Password button to select the desired password. Screens will enter that password on the remote computer for you.
Note: AgileBits has retired the extension Screens is relying on to access your 1Password account. Unfortunately they haven't released an updated extension and we believe they are not planning to do so. This feature is no longer supported and could break in the future.
