Downloading the apps from the Google Play Store

You must be granted access to download the apps from the Google Play Store. You will need to provide the email address that you use to sign in to the Google Play Store on your Android device. Once your email address is added it may take several hours before you can access the apps.

There are two apps. The U2F Client is our app that we will be distributing through the Play Store. It is used by relying party apps that want to use U2F. The U2F Demo App is an example of a relying party app. There is an API that the relying party will use to work with the SurePassID U2F Server and U2F Client.

  •  NFC Security Key
    NFC security keys of any form factor can be used. To use the NFC device, place it on the back of the phone until the operation is completed.

    Bluetooth Low Energy (Smart) security keys will automatically be connected if they are advertising the U2F Service.
