SoftU2F is a software U2F authenticator for macOS that emulates a hardware U2F HID device and performs cryptographic operations using the macOS Keychain. It works with Chrome, Safari, Firefox, and Opera's built-in U2F support, but the project is now deprecated since browsers support Touch ID natively.

Use cases

• use Touch ID as a U2F security key on macOS
• software FIDO U2F authenticator for two-factor login
• register and authenticate with U2F in Chrome or Safari without hardware key
• emulate a USB U2F HID device on Mac
• test U2F flows with Yubico demo site

When to choose

• you need a software U2F token on an older macOS setup where browsers lack native Touch ID support
• you want to experiment with U2F registration and authentication flows without buying a hardware key

When to avoid

• you are on macOS 11+ or recent Chrome, which support Touch ID for U2F natively
• you need the strongest security, since keys stored in the Keychain are accessible to local malware unlike hardware authenticators
• you need a maintained project - SoftU2F is deprecated with known unfixed compatibility issues
