Best Authentication Software for JavaScript

With just a few lines of code, LoginID enables websites and apps to integrate FIDO/FIDO2 certified multi-factor authentication via our easy to use SDKs and APIs. Our platform leverages the biometrics on the end user's device to create a private key, public key pair that allows for seamless strong customer authentication. No app installation is required and the private key is stored securely on the end user's device, never leaving. Additionally, LoginID offers Transaction Confirmation, where a transaction can be cryptographically signed providing proof of the user’s confirmation of that specific transaction, which is perfect for merchants who want payment authentication services. LoginID is aligned with PSD2, GDPR, CCPA, and HIPPA. We have SDKs for iOS, Android, React-Native, Web, Python, Java, and Node as well as a WordPress Plugin.
