YubiKeys offer a robust way to protect your online accounts from phishing and hacking. Why? Because it’s a physical key. This makes it very resistant to common attack methods.
What is a YubiKey?
A YubiKey is a small device, similar to a USB stick, that you use to securely log into your online accounts. It acts as a physical key that you need to have with you to access your accounts.
How Does It Protect You?
- Physical Presence: To log in, you simply plug the YubiKey into your computer or tap it on your phone and touch it. This ensures that only someone with the physical key can access your account, making it impossible for hackers to log in remotely.
- Domain Binding: YubiKeys are designed to work only with the specific websites they are registered with. If you accidentally visit a fake (phishing) website, YubiKey will not authenticate, preventing the hacker from stealing your login information.
- No Shared Secrets: Unlike traditional methods like SMS codes, which can be intercepted, YubiKeys use a unique cryptographic process that does not transmit any secrets over the internet. This makes it much harder for hackers to steal your credentials.
Why is This Important?
- Prevents Account Takeovers: By requiring the physical presence of the YubiKey, it becomes nearly impossible for hackers to take over your account, even if they have your password.
- Reduces Phishing Risks: Since YubiKey will not authenticate on fake websites, it protects you from phishing attacks where hackers try to trick you into giving away your login details.
Yubikey Options and Pricing
YubiKeys are available in various form factors, including USB-A and USB-C options. The YubiKey 5 NFC, for example, costs $50 USD and is a popular choice.
