SaaS PasswordFree Authentication™️ For Customers

This SaaS passwordless authentication for customers offering is an API-enabled internet security service that provides an easy-to-implement, easy-to-use, affordable, and scalable #PasswordFree Authentication™ solution for developers and online businesses that require a customer to register or log in to a web portal or mobile application. SaaS #PasswordFree Authentication™ powers a world-class customer experience by utilizing a visual-only confirmation, allowing the customer to confirm their authenticity by using a picture and a number (no typing required), making the authentication process easier and more secure than the popular One Time Password (OTP) methods that require a user to type a 6-8 character code. With a simple look, click, or tap, customers are taken through at least three factors of authentication – something they know, something they have, and something they are (biometric). And there’s more… The customer's security is enhanced by the Identité® patented Full Duplex Authentication®, an intelligent Multi-Factor Authentication (MFA) security process, which not only authenticates a user’s digital token but also requires the server to authenticate to the customer before exposing the user’s token. This essentially eliminates phishing, impersonation, and “Man-in-the-Middle” attacks. SaaS #PasswordFree Authentication™️ for Customers by Identité® is a revolutionary backbone for the digital security of internet businesses, with the latest technology, and functionalities that will improve and modernize your business’s internet security standards, and it creates a more secure, simple #PasswordFree™ experience for your customers.

SenseCrypt Biometric Identity Platform

SenseCrypt Authenticator is a passwordless, phishing-resistant identity platform that verifies a live person rather than a password, code, or device-bound key. Each sign-in turns a face into a non-reversible, single-use, quantum-safe token; no biometric template is ever stored, so there is nothing to breach, link, or reverse. Face matching runs on the device. It's a complete identity provider, not just an app: OIDC, OAuth 2.0 (PKCE, PAR), SAML 2.0, SCIM 2.0 and CIBA, with roles, audit logging, and multi-tenant isolation — built to drop into your existing stack and pass enterprise security review. Deploy as SaaS or on-prem, and embed it in your own apps with the mobile SDK. Backed by verifiable rigor: evaluated in NIST's FRTE under its own name since 2021, iBeta ISO 30107-3 Level 1 & 2 certified for presentation-attack detection, and protected by a granted US patent.

Thales FIDO2 Devices & Security Keys

FIDO-compliant authenticators from Thales Group provide a practical, standards-based approach to passwordless authentication. By replacing passwords with FIDO2 security keys, organizations reduce exposure to phishing and account takeover while simplifying user access and complying with the highest security standards. Built on asymmetric cryptography, Thales FIDO2 hardware security keys are phishing-resistant and protect against man-in-the-middle attacks by binding credentials to trusted domains and storing private keys securely on the device.  Available in multiple form factors, including USB tokens and smart cards, these hardware keys support authentication across devices such as laptops and mobile phones as well as shared workstations. Users authenticate themselves. Security keys provide the necessary authentication factors, including something you have (physical token), something you know (PIN) or something you are (fingerprint), and something you do (touching token edge). They support FIDO2.0, FIDO2.1, WebAuthN, U2F. In addition, Thales hybrid FIDO2 authenticators support PKI, enabling digital signature, file encryption and phishing resistant authentication based on certificates to access legacy digital resources and FIDO to access modern digital resources.  Thales hybrid FIDO smart cards support physical access, enabling the deployment of converged badges for digital and physical access in your organization.
