Question: I need a system that provides passwordless authentication options and integrates with existing SSO solutions to strengthen security.

First, SecureAuth offers a full-featured passwordless continuous authentication platform. It includes support for continuous authentication, invisible MFA, and device trust, as well as a host of other important features like passwordless authentication with Passkeys and FIDO2-approved technologies. SecureAuth also works with SSO products like Okta and Microsoft, so it's a good option for companies that want to improve security while also improving user experience.

Another good option is Arculix, which offers next-gen access management and continuous authentication.
