1. Open one of the websites that support FIDO U2F.

2. Log in to the website and enable two-factor authentication in your account settings. (In most cases you will find a link to the documentation of the supported web service at dongleauth.com)

3. Register your Nitrokey in the account settings by touching the button to activate the Nitrokey. After you have successfully configured the device, you must activate the Nitrokey this way each time you log in.

You are now ready to go.

Important

The Nitrokey App can not be used for the Nitrokey U2F.

Troubleshooting (Linux)

• If the Nitrokey is not accepted immediately, you may need to copy this file 41-nitrokey.rules to etc/udev/rules.d/. In very rare cases, the system will need the older version of this file.

• After copying the file, restart udev via sudo service udev restart.
