Set up Fido U2F app

Fido U2F is a two-factor authentication method (2FA) developed by the FIDO Alliance. It works with several web services, like Facebook, Dashlane, Gmail, Dropbox, GitHub, etc. 

For each of these web services, you need to set up the security parameters of your account to register your Nano S or your Blue as a second factor security key to authenticate on it. This second factor of verification will improve the security of your loging in processes, as you will be first required your login and password, second an authentication via your Nano S.
