Lockdown works with all online services that are compatible with Google Authenticator, and includes features not found in other two-factor authenticator services, like the ability to sync keys across multiple devices, store recovery codes inside the app, as well as iCloud backup functionality.
Here's a full list of features offered by Lockdown:
Ability to sync your account information via iCloud to multiple devices (and soon to Lockdown for Mac)
Ability to restore your accounts when upgrading to a new device, or when restoring iOS to an existing device
Automatic setup with a 2D barcode provided by an online service
Ability to sort and find accounts based on favorites
Ability to store backup Recovery Codes for emergency account access
You can share the one-time passwords generated by Lockdown through Copying, Messaging, or Email.
One-time passwords can be spoken using the dictation feature in iOS. Simply double-tap the one-time password to have it spoken for hands-free typing, or use the share menu options.
An update to Lockdown is currently in the works, which will include Touch ID support, and a second update is being planned that will see the launch of a Safari extension that allows users to generate onetime passwords directly from the browser.
