Two-factor authentication app Authy has been updated to version 17.0. You can now get your most important keys right in the Notification Center.
Authy's Today widget will load up to five authentication keys at a time. If you choose to use the widget, but don't want to expose your keys, open Authy, and go to Settings > My Account > Protection Pin, and make sure that Protect Entire App is switched on. The entries in the widget will say Locked, and tapping one of the entries will take you to that service's key in Authy, now protected by your pin.
You can download Authy's 17.0 update from the App Store now.
