YoKey security keys protect your online accounts from fake login pages (phishing). They replace SMS codes and authenticator apps: plug in the key, touch it, and you are signed in. The key checks the site's real web address before it responds, so a fake page gets nothing back.
Every model is certified to FIDO U2F and FIDO2, built on NXP chips, and needs no software. It works with any service that supports security keys, including Google, Facebook, Instagram, Microsoft, Apple and GitHub.
Choose the model that fits your port:
- USB-A: YoKey 7A USB-A, and the 7A Nano, small enough to leave plugged in
- USB-C: YoKey 7C Nano
- Plug into a computer and tap an Android phone or iPhone over NFC: YoKey 8A NFC (USB-A) and 8C NFC (USB-C)
- Fingerprint reader on the key, so it confirms it is really you: YoKey 9A Bio (USB-A) and 9C Bio (USB-C)
- iPhone or iPad with a Lightning port: YoKey 7Ci Duo, with both Lightning and USB-C connectors
Register two keys: one for everyday use and a backup kept somewhere safe. If you lose the main key, you can still get into your accounts.
