Users’ usernames and passwords are used throughout the normal authentication process. On the other side, passwords are easy to forget, misplace, or have stolen. As a result, in the current digital context, they are a less reliable technique of verification. Passwordless authentication is turning into increasingly more extensive due to its developing reputation and stepped forward security. Yet there are issues with key control with passwordless authentication.
The user does not need to enter a password to access a system or application while using passwordless authentication. To authenticate the user, biometrics, hardware tokens, or one-time codes are employed instead. These systems are more secure and resist phishing and credential stuffing attacks.
The usage of biometrics is one of the major challenges with passwordless authentication. To authenticate users, biometrics employ distinguishing physical attributes such as fingerprints, iris scans, and face recognition. Biometrics, although more secure than passwords, are not without faults. Biometric information can be stolen and exploited for malicious reasons. As a result, it is critical that biometric data be encrypted and securely kept.
Another common type of passwordless authentication is hardware tokens. Hardware tokens are physical items that create one-time codes for authentication. These devices are more secure than passwords since they are not prone to phishing and keylogging assaults. However, hardware tokens can be stolen or lost, putting system security at risk.
It is vital to ensure that the keys are safely kept using passwordless authentication. This means that biometric data, hardware tokens, and one-time codes are encrypted and stored securely. It also signifies that the keys are only accessible to authorised persons.
