Password-Less Authentication: Check benefits, popular methods for implementations

As time goes on, more and more companies are joining the trend of password-less login. You may have already encountered, or will soon come across, passkeys, which is the new standard set by the FIDO Alliance. Recently, tech giants like Apple, Microsoft, and Google have committed to creating support for password-less sign-ins. With these major companies driving the initiative, a future without passwords could be a possibility.

Password-less authentication

Moving towards password-less authentication for your website or app can provide immediate benefits to both business and customers. Password-less authentication can eliminate security breaches that may arise from poor password choices and management, security risks to personal information, and the frustration that comes with forgotten passwords.

As people increasingly prefer mobile-friendly experiences, they also want the ability to switch between devices effortlessly and at their convenience. As a result, customers may be more willing to accept password alternatives, particularly for accounts that contain sensitive data. Another added benefit for your customers, as well as your conversion and login rates, is that password-less authentication reduces the number of steps they need to take in order to transact with you.

What are some popular Password-less login methods?

Biometric Authentication: This password-less method uses physical data, such as fingerprints or facial recognition, to authenticate users and grant access to their accounts. Biometric authentication is convenient and provides a high level of security, but it requires users to have devices that support these features.

Magic Links: With magic links, users can log in to their accounts by providing their email address and receiving a unique link via email that they can use to access their account. However, magic links have a short life span and may be slower than other methods.

One-Time Passwords (OTP): OTP is a popular method for password-less authentication, where customers receive a one-time password through email or SMS to access their accounts. However, deliverability can sometimes be an issue, and users may accidentally request multiple OTPs.

Push Notifications: With push notifications, the app sends a notification to a registered device to open the app, using the device itself as the factor for authentication. However, the user is required to install the brand's application on their mobile device to receive push notifications.

Authenticator Apps: Authenticator apps generate time-based one-time codes that can be used to log in to accounts. The user must have the app installed on their device, and the device should be connected to internet to receive the password. Authenticator apps are often used as a second-factor authentication mechanism.
