FEITIAN OTP Token and Security Key Differences

The main differences between FEITIAN OTP hardware tokens and FIDO U2F Security keys are

FIDO U2F Security Key

• The USB device protects the user’s private keys with a tamper-resistant component known as a secure element (SE)
• Security Key authenticators don’t require any special drivers
• Users can easily enroll their own devices with Duo’s service
• Only supported by Duo integrations that use the Duo Prompt
• A Security Key’s real-time challenge-response protocol protects against phishing attacks

OTP Hardware Tokens

• Wide range of compatibility with any broswer or application
• Must be managed by Duo administrators as hardware tokens
• Can be used with append mode and the Duo Authentication Proxy
• OTP codes can still be phished to an adversary (known as man-in-the-middle/man-in-the-browser attacks)
