U2F Zero is an open source hardware U2F security token for two-factor authentication, built on a small USB device with secure key storage. It is explicitly unmaintained and superseded by the Solo FIDO2 key.
Use cases
- build my own U2F security key
- two-factor authentication for Google and GitHub
- open source hardware 2FA token
- cheap hardware security key for keychain
- U2F token with unlimited registrations
When to choose
- you want to build your own U2F token from open source schematics
- you need a low-cost hardware 2FA key and accept U2F-only support
When to avoid
- you need FIDO2 or passwordless login - use SoloKeys instead
- you want a maintained, supported product
- you need protection against targeted physical side-channel attacks
