better_auth-passkey

Passkey/WebAuthn plugin package for Better Auth Ruby.

Installation

Add the gem and require the package before configuring the plugin:

gem "better_auth-passkey"

require "better_auth/passkey"

auth = BetterAuth.auth(
  secret: ENV.fetch("BETTER_AUTH_SECRET"),
  database: :memory,
  plugins: [
    BetterAuth::Plugins.passkey
  ]
)

Notes

This package depends on the maintained webauthn gem. Keeping passkeys outside better_auth avoids installing WebAuthn dependencies for applications that do not use passkeys.
