# Security Keys (U2F)
|
|
|
|
**Authelia** offers authentication using Security Keys like [Yubikey](Yubikey)
|
|
which are one of the most secure way to authenticate and get authorized.
|
|
It is already available for Google, Facebook, Github accounts and more.
|
|
|
|
The protocol requires your security key to enrolled before authenticating.
|
|
|
|
To do so, select the *Security Key* method at the second factor stage and
|
|
click on the link *Not registered yet?*. This will send a link to your
|
|
user email address. This e-mail will likely be sent to
|
|
https://mail.example.com:8080/ if you're testing Authelia and you've not
|
|
configured anything.
|
|
|
|
Confirm your identity by clicking on **Register** and you'll be asked to
|
|
touch the token of your security key to enroll.

### Why don't I have access to the *Security Key* option?
