Credential-free demo: this page intentionally omits email and password fields. Use it for design, training, or UI flow demonstrations. For production, implement secure server-side auth and strong transport encryption.

Sign in securely — Without collecting credentials (demo)

This demo demonstrates alternative methods and guidance for signing in without directly entering email/password on the page. Examples include hardware wallet unlock, single-use magic links sent to verified emails (server-handled), and OAuth flows with identity providers.

Recommended secure sign-in patterns

  • Hardware wallet + local device unlock: Use device-backed authentication where private keys stay on the hardware device.
  • Magic links (server-side): Send a one-time link to a verified email; the client should never display or store plaintext credentials.
  • OAuth / SSO: Redirect to trusted identity providers so credentials are handled off-site by the provider.
  • WebAuthn / Passkeys: Use browser-native cryptographic credentials for phishing-resistant sign-in.
