If you’re looking for an extra level of security for your personal accounts and data, YubiKey is a great way of securing your weak points. This small, yet powerful hardware device is like a physical key that, instead of unlocking a door, unlocks your online life.
It can be used as 2-factor authentication for the likes of Google Mail, Facebook, Last Pass, and your Blockchain.com wallet. YubiKey provides an additional element after login with a username and password to verify that it’s you who’s trying to access your online accounts.
2 Factor Authentication
18 million login credentials are compromised every day and one of the most important steps to securing your online presence is by enabling a form of 2-factor authentication. Using 2-factor authentication (or 2FA) is when you are asked to enter in your username and password and then another piece of proof that you are who you say you are.
One of the most common is a text that you receive on your mobile phone with a string of numbers, characters, or a combination of both. However, this can come with an element of risk as a hacker could also potentially compromise this system too. So another way is either using a secure app on your phone like Google Authenticator or Authy or by using a hardware device like a YubiKey 5 NFC.
What is a YubiKey 5 NFC?
A YubiKey 5 NFC is a small hardware device made by the company Yubico. These battery-free devices plug into your computer and along with your password provide you with 2 layers of 2 step verification. This type of verification cannot be intercepted by a hacker as they would physically need your device to get access to your accounts, along with your username or email and password.
The devices are also very durable, waterproof and crush resistant and come with a keyhole ring and chain so that you don’t lose it. Using both a USB-A connector to connect to your computer and wireless NFC for your phone. NFC which stands for “Near Field Communication” allows phones, tablets, laptops, and other devices to easily share data with other NFC-equipped devices.
Once you register your YubiKey with services, just tap your YubiKey for easy, strong two-factor authentication, for computers, networks, and online accounts. With no need for text messages or one-time passcodes.
The YubiKey can be purchased individually, as a pack of 2, 10 or 50 which is ideal for teams.
Where Can I Buy a YubiKey?
What Happens If I Lose My YubiKey?
Its recommended that you purchase more than 1 YubiKey to use as a backup in case you were to lose your YubiKey. This spare, should be kept somewhere secure and safe. Also, ensure that you have another way to enter your online accounts incase you do. For example, with Google Mail ensure that you take note of your Back-up Codes or Recovery Seeds or Phrases with the likes of Blockchain.com.
What Applications Support Yubikey?
YubiKey 5 NFC adhere to an industry-standard named Universal 2nd Factor, or U2F. This standard combines hardware-based authentication with public-key cryptography making it very hard to compromise.
The YubiKey works with well-known services that support U2F and FIDO2, like Facebook, Google, Blockchain and Dropbox. There are also computer login options for Macs and Windows PCs. Plus, you can even set up your YubiKey with password management like Dashlane or LastPass, and developer platforms like Github and Bitbucket.
