With so many services rendered and interactions taking place online, users have an inordinate number of accounts. And that means just as many usernames. Each time users log in on a different device, they have to authenticate with the correct username for each platform, app, and service. This is a tedious and time-consuming process that can easily be avoided.
Usernameless authentication lets customers approve transactions without first having to type in a username. Be it a standard platform login attempt, an identity verification process during an online or phone support session, et al., usernameless authentication gives users a smooth authentication experience that is both secure and convenient.
Usernameless authentication eliminates the need to remember which username was used for which service. It also speeds up the login process, especially on mobile devices with their significantly smaller keyboards. But there are even more benefits to usernameless authentication:
There are a number of possibilities to implement usernameless authentication. These may rely on QR codes, push codes, or biometrics Here are three examples:
As a precondition, the user has already been registered to the system and has installed and set up a branded access app on their mobile phone. Ideally, they used a biometric authentication method such as FaceID.
A user, currently unknown, wants to log into your website. You issue a QR-code that is tied to the log-in transaction, but has no user specified in it. The user scans the QR-code with the branded app on their phone, confirms that they want to log in and authenticate with their FaceID. In the background you keep polling the status end-point for this transaction with its token. While the user is still going through the motions, the transaction is still pending. But as soon as the authentication is successfully completed, the status endpoint returns a success data object that has the userId, and your back-end systems can link the successful transaction, the log-in, to that user account and give them access to your website.
Why Is Passwordless Authentication Without Usernames Convenient?
Usernameless authentication simplifies the authentication process for users as they do not have to remember a separate username.
How Does Usernameless Authentication Increase Security?
Usernames can be easily guessed or obtained through social engineering, making them a weak point in the authentication process. Userless authentication can provide an additional layer of security by using a more unique identifier such as an email address or phone number.
How Does Usernameless Authentication Enhance the User Experience?
Usernameless authentication can provide a seamless and frictionless user experience, especially for mobile users. Users can quickly authenticate by clicking on a link.
How Does Usernameless Authentication Increase Data Protection?
Usernameless authentication can be more privacy-friendly than traditional authentication methods, which often require users to reveal personal information such as their username or email address.
