What method allows a user to log in to a computer system without entering a password?

Passwordless authentication is a method that enables users to log into a computer system without the need to enter a traditional password. This approach enhances security by eliminating the risks associated with password management, such as forgetfulness, weak passwords, and phishing attacks.

Typically, passwordless authentication can involve various techniques, such as using biometric data (like fingerprints or facial recognition), one-time codes sent via SMS or email, or hardware tokens. By relying on these alternative forms of identification, passwordless systems make it easier for users to access their accounts while also potentially increasing security through more robust and less susceptible methods compared to conventional passwords.

This method is gaining popularity as organizations shift towards improving user experience and reducing the chances of unauthorized access. The focus is on ensuring that authentication remains reliable and secure without compromising user convenience.

The other options pertain to different authentication methods or processes that involve passwords or multiple steps for access, which is why they do not fit the description of logging in without entering a password.
