What authentication method involves a physical device used to verify identity alongside a password, without relying on biometric data?

The correct answer involves security keys, which are physical devices used in conjunction with a password for authentication purposes. This method enhances security by requiring the user to possess a tangible item that verifies their identity. When a user attempts to log in, they must enter their password and then authenticate using the security key, which generates a unique code or uses cryptography to facilitate the login. This two-factor authentication approach adds a layer of protection against unauthorized access, as an attacker would need both the password and the physical security key to gain access.

In contrast, password managers store and manage passwords securely but do not inherently involve a physical device for authentication. Two-factor authentication via SMS requires a text message to a phone, which, while an added security measure, doesn't utilize a physical device directly tied to the user. Identity management systems encompass a broader range of tools and processes for managing user identities and credentials but do not specifically refer to the physical device element needed to verify identity alongside a password.
