Hardware security keys are physical devices that protect our online accounts from hackers and scammers. They work by adding an extra layer of security beyond just passwords. When you try to log in to an account, you need both your password and your security key, making it much harder for someone to break in. These small devices connect to your computer or phone through USB, NFC, or Bluetooth.
Two-factor authentication (2FA) has become essential for keeping our accounts safe, and hardware keys are the strongest form of 2FA available. Unlike authentication apps or text messages, hardware keys can’t be intercepted or copied by hackers. They’re especially important for people with sensitive information like financial records, business data, or personal photos.
When shopping for a security key, pay attention to compatibility with your devices, the connection types (USB-A, USB-C, NFC, or Bluetooth), and supported authentication standards like FIDO2. Price is also important, but investing in a quality key from a trusted brand is worth it for the protection you get. We spent weeks testing fifteen popular security keys across different devices and services to find the best options for most people in 2025.
