Abstract: A browser-based full-duplex password-less authentication system provides secure access to third-party services without requiring password entry. Upon attempting to access a service, an access server generates a visual representation and at the browser, a one-time password is converted into a second visual representation, both have an image and alphanumeric characters and are displayed simultaneously on a display of a client device. The user compares the first and second visual representations and confirms that they match. Security is maintained through Transport Layer Security (TLS) with specific cipher suite requirements, digital certificates, and protection against man-in-the-middle attacks. This approach eliminates password management burdens while providing strong security through visual verification and cryptographic protections, all within the user's browser environment.

Abstract: Upon an attempt to access a service of a third-party server, full-duplex password-less authentication provides a one-time password to the user displayed at the client device and at a mobile device associated with the user. The user verifies the access by comparing the one-time password displayed at the mobile device and the one-time password displayed at the client device. In some embodiments, the one-time password is displayed as a picture while in other embodiments, a combination of a picture the one-time password is displayed as a picture and a set of alphanumeric characters for ease in making the comparison. The user determines whether to accept or deny the authentication sequence after a simple visual comparison.
