Future-proof security

Advanced Security: Checked

Easily deploy Man-in-the-Middle attack resistant auth system & Multi-Factor Authentication (MFA). Stop all attacks, including ransomware, push attacks and account takeover with passwordless authentication secured by public-key cryptography and full-request signatures.

End-to-end encryption.  During the authentication, a new end to end encryption system protocol ensures no active or passive MITM attack is effective

No cookies used.  We not use cookies to function, so even if the user browser doesn't accept cookies, the authentication will still work

Private credentials.  The private key never leaves the browser and can never be stolen by MITM attacks. After the authentication, signatures guarantee the user claims

1async function signRequest(requestInit) {
2  const { method, headers, body } = requestInit;
4  // Load current user and get their public key ID
5  const user = await auth.getCurrentUser();
6  const keyId = user.subSigKeyId;
8  const data = Buffer.from(body || Buffer.alloc(0));
10  // Create the signature by signing the message
11  let sig = await user.signMessage(data);
13  // Encode the signature to Base64
14  sig = Buffer.from(sig).toString('base64');
16  return {
17    method,
18    headers: {
19      ...headers,
20      // Add the signature header
21      'x-signature': `${keyId};${sig}`
22    },
23    body
24  };
