It requires users to provide two different types of credentials for authentication. Typically, this involves a combination of something the user knows (e.g., a password) and something the user possesses (e.g., a physical tokenSession Hijacking: An attack where an unauthorized user take... or a one-time passwordDigital Wallet (or e-Wallet): A virtual wallet where individ... generated by a mobile app).

Advantages of 2FA:

• Stronger security: Combining two factors significantly reduces the likelihood of unauthorized access.
• Ease of use: Although requiring an extra step, 2FA is easily implemented and understood by users.
• Broad compatibility: 2FA is supported by numerous platforms, making it widely deployable.

Stage 2: Biometric AuthenticationBiometric Authentication: A security process that relies on ...

Biometric authentication utilizes unique physical or behavioral characteristics of an individual for identification. Common biometric factors include fingerprints, facial recognition, voice recognition, and iris scanning.

Benefits of Biometric Authentication:

• Enhanced security: BiometricsIoT (Internet of Things): The network of physical devices em... are difficult to replicate or share, making authentication more secure.
• User convenience: Biometric identifiers are innate to the user, eliminating the need to remember passwords or carry physical tokens.
• Improved user experienceDigital Native: A person born during the age of digital tech...: Biometric authentication provides quick and seamless access for users.

Stage 3: Contextual AuthenticationMFA (Multi-Factor Authentication): A method of confirming a ...

Contextual authentication considers additional factors beyond mere usernames and passwords. It analyzes contextual elements such as location, IP address, time of access, and device information to determine the legitimacy of a login attempt.

Advantages of Contextual Authentication:

• Enhanced security: By validating additional contextual information, suspicious login attemptsCAPTCHA (Completely Automated Public Turing test to tell Com... can be detected and blocked.
• Frictionless user experience: Contextual authentication adds extra security layers without significantly impacting the user experience.
