Getting Started

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 and with the Nitrokey App 2.

Passwordless Authentication

1. Open a web page that supports FIDO2.

2. Log in to the website and go to “Set up security key” in the security settings of your account.

3. Now you need to set a PIN for your Nitrokey 3.

4. Touch the button of your Nitrokey 3 when prompted.

5. 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.

Two-Factor Authentication (2FA)

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 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.

You are now ready to go.
