+
+The use of security keys can improve your security by providing a second
+authentication source that cannot be easily stolen or copied (similar to
+the protection provided by mechanical keys for the door of your home or
+apartment), which reduces the risk of impersonation.
+
+The example configuration detailed below showcases what minimal
+configuration needs to be made on your Guix System to allow the use of a
+Yubico security key. We hope the configuration can be useful for other
+security keys as well, with minor adjustments.
+
+@subsection Configuration for use as a two-factor authenticator (2FA)
+
+Two be usable, the udev rules of the system should be extended with
+key-specific rules. The following show how to extend your udev rules
+with the @file{lib/udev/rules.d/70-u2f.rules} udev rule file provided by
+the @code{libfido2} package from the @code{(gnu packages
+security-token)} module and add your user to the @samp{"plugdev"} group
+it uses:
+
+@lisp
+(use-package-modules ... security-token ...)
+...
+(operating-system
+ ...
+ (users (cons* (user-account
+ (name "your-user")
+ (group "users")
+ (supplementary-groups
+ '("wheel" "netdev" "audio" "video"
+ "plugdev")) ;<- added system group
+ (home-directory "/home/your-user"))
+ %base-user-accounts))
+ ...
+ (services
+ (cons*
+ ...
+ (udev-rules-service 'fido2 libfido2 #:groups '("plugdev")))))
+@end lisp
+
+After re-configuring your system and re-login to your graphical session,
+you can verify that your key is usable by launching:
+
+@example
+guix shell ungoogled-chromium -- chromium chrome://settings/securityKeys
+@end example
+
+and validating that the security key can be reset via the ``Reset your
+security key'' menu. If it works, congratulations, your security key is
+ready to be used with applications supporting two-factors authentication
+(2FA).
