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.

Note: Fido U2F is not required to secure cryptocurrencies. It simply provides additional functionality to your Ledger device. 


  • A Ledger Nano S or Ledger Blue
  • The latest firmware version installed on your device. 
  • Your device should already be configured with a 24 word recovery phrase and a PIN code.
  • The Ledger Manager should be downloaded and installed.

Note: Each time you reinstall the Fido U2F application on your Ledger device, it will have to be reconfigured with each service it is being used with. Never rely on Fido U2F as the sole means of accessing your accounts on other services. Refer to this article for more information.
