What is passwordless login?

Passwordless login is a type of authentication that does not require users to enter a traditional password to access their accounts or systems. Instead, passwordless login methods use other factors to authenticate the user's identity. This approach is becoming increasingly popular due to concerns about password security, such as the risk of data breaches and the difficulty of remembering complex passwords.

There are several types of passwordless login methods, including:
Biometric authentication: This method uses unique biological characteristics, such as fingerprints, facial recognition, or iris scans, to authenticate the user's identity.

Token-based authentication: This method uses physical devices, such as security keys or smart cards, to authenticate the user's identity.

Email or SMS-based authentication: This method sends a one-time code to the user's email or mobile device, which they must enter to authenticate their identity.

Single sign-on (SSO): This method allows users to log in to multiple systems or services with a single set of credentials, eliminating the need for separate passwords.

Passwordless login methods offer several benefits, including increased security and convenience for users. By eliminating the need for traditional passwords, passwordless login methods can reduce the risk of password-related security incidents, such as phishing and password guessing attacks. Additionally, passwordless login methods can be more convenient for users, as they do not need to remember or enter complex passwords.

However, it's important to note that passwordless login methods are not foolproof and can still be vulnerable to certain types of attacks, such as social engineering or device theft. Therefore, it's important to use passwordless login methods in combination with other security measures for added protection.
