Nitrokey 3 with Linux¶
The Nitrokey 3 supports two-factor authentication (2FA) and passwordless authentication:
With passwordless authentication, entering a password is replaced by logging in with the Nitrokey 3 and a PIN.
With two-factor authentication (2FA), the Nitrokey 3 is checked in addition to the password.
The Nitrokey 3 can be used with any current browser.
Currently the Nitrokey App can not be used for the Nitrokey 3.
Open a web page that supports FIDO2.
Log in to the website and go to “Set up security key” in the security settings of your account.
Now you need to set a PIN for your Nitrokey 3.
Touch the button of your Nitrokey 3 when prompted.
Once you have successfully configured the device, you will need to activate your Nitrokey 3 this way each time you log in, after entering your PIN.
Open one of the websites that support FIDO U2F.
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.)
Register your Nitrokey 3 in the account settings by touching the button to activate the Nitrokey 3. After you have successfully configured the device, you must activate the Nitrokey 3 this way each time you log in.
