1. Purpose and Functionality
* MFA: Enhances security by requiring multiple forms of verification. Its main focus is to add layers of security to the authentication process.
* SSO: Enhances user convenience by allowing access to multiple applications with a single set of credentials. Its main focus is to simplify the login process and improve user productivity.
2. Security vs. Convenience
* MFA: Prioritizes security. While it may add a step or two to the login process, the trade-off is a significantly higher level of protection against unauthorized access.
* SSO: Prioritizes convenience. By reducing the number of login prompts, it makes the user experience smoother and can potentially increase productivity.
3. Use Cases
* MFA: Ideal for securing access to sensitive data, critical systems, and applications where high security is paramount. This includes financial services, healthcare, and any environment handling personal or confidential information.
* SSO: Best suited for environments where users need seamless access to multiple applications, such as corporate settings with integrated software suites (e.g., Google Workspace, Microsoft Office 365).
4. Implementation Complexity
* MFA: Implementation can be more complex and may require additional infrastructure, such as biometric scanners or hardware tokens, depending on the chosen factors.
* SSO: Generally easier to implement, especially with modern cloud-based solutions that integrate with existing directory services like Active Directory or LDAP.
5. Impact on User Behavior
* MFA: Encourages users to adopt more secure practices, such as not relying solely on passwords and being more vigilant about security.
* SSO: Encourages users to adopt a centralized identity management approach, reducing password reuse and the risk of credential fatigue.
