Frequently asked questions

What is 2FA?expand_more

2FA is a method to confirm a user’s claimed online identity by using a combination of two different types of factors. Factors used for 2FA include something that you know (e.g. password or PIN), or something that you have (e.g. a security key or phone) or something that you are (e.g. facial recognition). For more detailed information, please visit our 2FA glossary page.

What is a YubiKey?expand_more

A single YubiKey has multiple functions for securing your login to email, online services, apps, computers, and even physical spaces. Use any YubiKey feature, or use them all. The versatility of the YubiKey requires no software installation or batteries and therefore is ready to use directly out of the package. Simply login to the service, add your YubiKey, and enjoy a more secure online experience.

What happens if I lose my YubiKey?expand_more

We always recommend securing your accounts with an additional YubiKey. However, if you do not have a spare Key and lose your YubiKey, we encourage you to have another form of 2FA added to your accounts to prevent being locked out of your accounts. Please note that if you do end up being locked out of an account, you will need to contact the service for account recovery help.

Is it important to have a Spare Key?expand_more

Yes, we at Yubico always recommend having more than one YubiKey. This way one key can be used as a primary Key, and the other can be used as a Spare Key. The importance of having a spare Key is well established. We have them for our most valuable assets in life – our houses, our cars, and our PO and safety deposit boxes. Not surprisingly, we also need spare keys for our digital devices! Having a spare Key gives you the assurance that if you lose your primary Key, you will not be without access to critical accounts when needing them most. In other words, with a spare Key you have no need to fear being locked out of any accounts, and no need to go through a lengthy recovery and identity verification process to regain access to each account.

Why isn’t NFC working on my new YubiKey, and how do I fix it?expand_more

To protect your security during shipping, NFC is temporarily disabled on your YubiKey. Activating it is easy: plug your YubiKey into any USB power source, like a computer, for at least 3 seconds. Once powered, NFC will be activated and ready to use. You can find more details here.

How do I unblock biometrics on my key?expand_more

After 3 unsuccessful attempts to authenticate using biometrics your YubiKey Bio will cease to prompt for the fingerprint and will fall back to PIN and regular touch, the primary authentication mechanism. The blocked biometrics state is indicated by a constant slow flashing of the amber LED, the one closer to the USB-contact.

To unblock biometrics, do the following:

Click here – Unblock biometrics

Enter the PIN for your security key.

When the green LED flashes, touch the bezel ring on your key.

Note that if you are not in the biometrics blocked state, the browser will ask you to authenticate using biometrics.
