https://github.com/danstiner/rust-u2f

A software-only Universal 2nd Factor token. Supports Google Chrome and Firefox on Linux. Written in Rust.

Security

Disclaimer: This is a personal project, I am not a security expert and make no guarantee of security.

Like any U2F authenticator this program provides a degree of protection against phishing and poorly chosen passwords. It does not provide the same level of protection against malware that a hardware authenticator does.

If your machine is compromised by malware, the attacker could steal a copy of the secret keys stored by this authenticator. In this situation you should immediately unregister this authenticator anywhere it is registered in addition to changing the passwords of any potentially compromised accounts. With a hardware authenticator secret keys never leave the device, so in the case of malware you can simply unplug from the infected machine and be confident your accounts are safe from further compromise.
