U2F Zero: Open-Source USB Security Key

U2F Zero supports the Universal 2nd Factor (U2F) authentication standard, is small, inexpensive, and easy to carry for strengthened logins to websites.

What is U2F Zero?

U2F Zero is an open source hardware USB security key that implements the Universal 2nd Factor (U2F) authentication standard. It was created to provide an easy-to-use and affordable security key option to help individuals strengthen the security of their online accounts.

The U2F Zero key is small in size, similar to a USB thumb drive, so it can conveniently be carried on a keychain or in a bag. It uses secure cryptographic protocols to provide two-factor authentication when logging into supported websites, such as Google, Dropbox, GitHub, and more.

When logging into an integrated site with U2F Zero plugged into the computer's USB port, the site prompts the user to touch the metal contact on the device to verify their identity. This helps protect against phishing attacks and authentication bypass vulnerabilities. Even if an attacker obtains a user's login credentials, they cannot access the account without physical possession of the U2F security key.

U2F Zero is open source, so its firmware and hardware designs are available for free. This allows security researchers and hobbyists to audit and build upon the platform. The device uses standard components to minimize costs, making secure two-factor authentication more accessible to typical internet users.
