What distinguishes a hardware token from other authentication methods?

A hardware token is a physical device specifically designed to enhance security by generating one-time passwords or codes used for authentication. This uniqueness is what distinguishes hardware tokens from other authentication methods. Unlike software tokens, which are applications running on devices, hardware tokens are standalone physical devices that usually generate time-sensitive codes, ensuring that the authentication is both secure and not reliant on an internet connection.

This method offers an added layer of security since the token itself is required to generate the password, making it more difficult for an attacker to gain access to accounts or systems. The reliance on a physical device can provide stronger security than software-based tokens, which may be susceptible to malware or device theft.

In contrast, options that involve software on mobile devices or the need for an internet connection pertain to different types of authentication methods that do not leverage the physical characteristics of a hardware token, while the notion of being less secure directly opposes the purpose of hardware tokens, which are typically regarded as having robust security features.
