Hardware Tokens
Hardware tokens are physical devices that are used to provide an additional layer of security for accessing sensitive information or systems. These tokens are typically small, portable, and can generate one-time passwords or codes that are required to authenticate a user's identity. They are often used in conjunction with usernames and passwords to prevent unauthorized access to computer networks, online accounts, or other digital resources. Hardware tokens can take the form of USB tokens, smart cards, key fobs, or mobile devices with built-in authentication capabilities. They are designed to be tamper-resistant and difficult to duplicate, ensuring that only authorized users can access protected resources.
