Beware of phishing attacks, Ledger will never ask for the 24 words of your recovery phrase. Never share them. Learn more


FIDO U2F is a two-factor authentication method (2FA) developed by the FIDO Alliance that is supported on the Ledger Nano S and Ledger Nano X devices. It works with several web services, like Facebook, Dashlane, Gmail, Dropbox, GitHub, etc. Check our Fido U2F page to learn more.

 Warning: Recent Scam Email about 2FA (two-factor authentication)

There has been a recent scam email circulating that prompts users to enable 2FA for "hardware wallets." Ledger does not send emails of this nature, nor do we enforce mandatory 2FA sign-in for all users. This is a phishing attempt, and you should not interact with this email under any circumstances. Do not click on any links or provide any personal information.

For information on legitimate reasons we may reach out via email, please refer to this article. Additionally, you can find a list of legitimate email addresses used by Ledger here.

  • FIDO U2F increases account security as both your password and Ledger device are required to log in.
  • FIDO U2F is not related to cryptocurrencies. It's an additional utility for your Ledger device.

 Key Takeaway

When it comes to restoring your recovery phrase on your Ledger hardware wallet, regaining access to your FIDO-protected account is a seamless process. All you have to do is reinstall the Fido U2F app, and you'll be able to access your account again, whether on the same device or a different one you own.

This means that you can set up another Ledger Nano device with the same 24-word recovery phrase and have the same FIDO U2F functionality on the restored or backup device.
