Passwordless authentication is a feature that allows users to log in to services and platforms without a password. Instead, the login process can be accomplished with biometrics like facial recognition and fingerprint scans.
Passwordless authentication processes are generally considered a form of multi-factor authentication (MFA). The use of additional authentication factors provides an added layer of security while maintaining a high level of ease and convenience.
Passwords are the weakest link in the authentication process. They are often either reused or not sufficiently secure to prevent an account from being compromised. This is the primary benefit of passwordless authentication. However, there are other benefits as well. These include:
As mentioned, passwordless authentication is a form of MFA. It relies on the use of a cryptographic key pair: the public key, which is held by the service provider, and the private key, which never leaves the user’s device. However, during an authentication process, it can be unlocked using biometrics (facial recognition or an iris or fingerprint scan) to complete the authentication process. Here’s how it works:
Why Does Password-Free Authentication Increase Security?
Passwords can be easily guessed or stolen through phishing, social engineering or other means. Passwordless authentication, on the other hand, uses more secure methods such as biometrics, one-time codes or security keys, which make it much harder for an attacker to gain unauthorised access to an account.
Why Is Passwordless Authentication Convenient?
With passwordless authentication, users do not have to remember complex passwords, which can be difficult and time-consuming. This makes the login process more convenient and efficient, resulting in a better user experience.
Why Does Passwordless Authentication Reduce Costs?
Passwordless authentication can also reduce the costs associated with password management and account recovery. By eliminating password resets and support requests, companies can save time and resources.
Why Does Password-Free Authentication Help With Regulatory Compliance?
Many government regulations require companies to implement strong authentication measures to protect sensitive data. Passwordless authentication can help companies meet compliance requirements and avoid costly fines.
