A security key is a physical device that will be uniquely associated with your Yahoo account after you enable it. Each time you sign in with your password, you'll be prompted to approve access to your account using your key. This prevents anyone who doesn't have your security key device from gaining access to your account.
Requirements to enable Security Key
- Your device needs a USB or a USB-C port to insert the security key or you can connect it wirelessly using Bluetooth or NFC.
- You must have the latest version of Chrome, Edge, Firefox, Safari or Opera.
- You need a FIDO Universal 2nd Factor (U2F) compatible security key that can plug into the USB or lightning port for your device or connect wirelessly using Bluetooth or Near Field Communication (NFC). Order a compatible security key from a retailer you trust.
