Other Authentication Methods Lesson Objectives By the end of the lesson, students should be able to: 1. Define authentication and explain its importance in security. 2. Identify and describe different authentication methods. 3. Compare and contrast the various authentication methods. 4. Explain real-world applications of these methods. Introduction to Authentication Authentication: Is the process of verifying the identity of a user or device before granting access. Traditional methods: usernames and passwords. Modern authentication improves security and convenience. Types of Authentication 1. Password-Based Authentication: -Users provide a unique password to gain access. -Must follow best practices (e.g., strong, complex passwords). 2. Two-Factor Authentication (2FA): -Combines two methods, such as a password and a one-time code sent to a device. 3. Biometric Authentication: - Uses unique physical traits, such as fingerprints, facial recognition, or retinal scans. 4. Token-Based Authentication: - Users are issued a physical or digital token for access (e.g., smart cards, USB keys). 5. Certificate-Based Authentication: - Involves digital certificates issued by trusted authorities to verify identity. Purpose of Authentication ∙ Prevent Unauthorized Access: Ensures that only authorized users can access systems or data. ∙ Protect Sensitive Information: Safeguards personal or organizational data from breaches. ∙ Verify User Identity: Confirms that the user is who they claim to be. Zero Login Authentication Uses AI and behavior analysis automatic login. No manual login required. Examples: Windows Hello, Face ID, Google Smart Lock. Pros: Seamless, secure and convenient. Cons: Requires advanced technology and convenient. Biometric Authentication Uses biological traits: fingerprint, facial recognition, retina scan and convenient. Examples: Smartphones, security systems. Pros: Hard to fake, quick, and user-friendly. Cons: Privacy concerns, costly, may fail under poor conditions Magnetic Stripe Cards Store data on a stripe (credit cards, hotel keys). Swiped on a reader to access data. Pros: Simple, widely used. Cons: Easy to clone, wears out. Smart Cards Contain a microchip for authentication. Examples: Bank cards, SIM cards. Pros: More secure than magnetic stripes. Cons: Needs a compatible reader. Physical Tokens Small devices used for authentication. Examples: USB security keys, key fobs. Pros: Strong security. Cons: Can be lost or stolen. Electronic Tokens Generate one-time passwords (OTP) or codes. Examples: Google Authenticator, SMS OTP. Pros: Adds extra security (2FA). Cons: Requires internet access. Comparing Authentication Methods Zero Login: High security, seamless but tech-dependent. Biometric: Secure but privacy concerns. Magnetic Stripe: Simple but easy to clone. Smart Cards: Secure but needs a reader. Physical Tokens: Secure but can be lost. Electronic Tokens: Extra security but internet-dependent. Conclusion Different methods suit different use cases. Multi-factor authentication (MFA) improves security. Future trends: AI authentication, quantum security, behavioral biometrics.
