Hardware Wallets (like Ledger and Trezor devices) are not limited to holding your private keys.

One thing that I find really interesting is using these devices as a security key for various websites, in addition or instead of using 2FA (Two Factor Authentication) like we do with Google Authenticator or Authy.

So this secured alternative is based on a standard called Fido U2F.
Chrome and Brave, at least, have support for it, although you can't authenticate wirelessly with your Nano X.

Ledger has made a really nice video explaining the setup on your device:

The idea is that instead of typing a code that changes over time (2FA), you simply connect your Ledger to your computer, unlock your ledger with your PIN code, run the Fido U2F app and approve various security popups and confirm the authentication with the Ledger device.

You can use this in two ways, depending on how the various websites handle it:

• As an additional security mechanism, meaning you'll still use 2FA and/or U2F,
• As another security mechanism, meaning you can't use 2FA anymore but need to use U2F instead!

Here are some few links on how to setup your Ledger for: Facebook, Dashlane, Google, GitHub, Dropbox.
