Explanation:
Answer: A passphrase
Explanation: A passphrase is a sequence of words or other text used to control access to a computer system, program, or data. It serves as a substitute for a traditional password during the authentication process. Passphrases are often longer and more complex than passwords, providing increased security against unauthorized access.
Answer:
Explanation:
During an authentication process, a password can be replaced by various factors to ensure secure access. Some common alternatives to passwords include:
1. Biometric Authentication: This method uses unique physical characteristics of an individual for authentication. Examples include fingerprint scans, facial recognition, iris scans, or voice recognition.
2. Two-Factor Authentication (2FA): In 2FA, along with a password, another factor is required for authentication. This could be something you have (like a security token or a code sent to your phone) or something you are (biometric data).
3. Multi-Factor Authentication (MFA): MFA goes beyond 2FA and requires two or more factors for authentication. It combines different types of factors like something you know (password), something you have (smartphone), and something you are (fingerprint).
4. Single Sign-On (SSO): SSO allows a user to access multiple applications with one set of login credentials. Instead of entering a password for each application, the user logs in once and gains access to all connected systems.
These methods provide added security compared to traditional passwords, as they make it harder for unauthorized users to gain access. Each method has its own advantages and can be used depending on the level of security needed for a particular system or application.
