FIDO U2F (Universal 2nd Factor) is a security standard that enables users to add an extra layer of protection to their online accounts. It is based on the principle of public-key cryptography, which means that each user has a pair of keys: a private key that is stored securely on the security key device, and a public key that is registered with the online service. When the user wants to log in, the service will challenge the security key to prove its identity by signing a message with the private key. The service will then verify the signature using the public key. This way, the user can authenticate without entering a password or a one-time code.
They are also resistant to phishing, malware, and man-in-the-middle attacks, as they only work with the original website that registered them.
How to Set Up a FIDO U2F Security Key?
To set up a Fido2 security key, you will need a compatible device and a Chrome-based browser. You will also need to enable two-factor authentication (2FA) on the online service that you want to use the security key with. Here are the general steps to follow:
- Log in to your online account and go to the security settings.
- Find the option to enable 2FA and choose the FIDO U2F security key as the method.
- Insert or connect your security key to your device and follow the instructions on the screen.
- You may be asked to name your security key and confirm your identity with another method, such as a password or a code.
- Once the registration is complete, you will see a confirmation message and your security key will be listed as a trusted device.
- You can repeat the process for other online services that support FIDO U2F security keys.
How to Use a FIDO U2F Security Key?
To use a FIDO U2F security key, you will need to have it with you when you want to log in to your online account. Here are the general steps to follow:
