What is passwordless authentication?

Passwordless authentication is a method of verifying a user's identity without requiring them to enter a password. Instead of using a password, passwordless authentication relies on alternative authentication factors such as biometric data, physical tokens, or one-time codes sent to a user's email or mobile device.

There are several methods of passwordless authentication, including biometric authentication, such as fingerprint recognition or facial recognition, physical tokens such as smart cards or USB keys, and mobile-based authentication, such as one-time codes sent via SMS or mobile apps.

Passwordless authentication offers several advantages over traditional password-based authentication, including increased security, convenience, and reduced risk of password-related issues such as forgotten passwords or weak passwords. However, passwordless authentication also has its own set of challenges and limitations, such as compatibility with existing systems and potential security risks associated with the use of mobile devices.
