You are assigned to implement Two-Factor Authentication in a Spring Security application. How would you approach this task, considering Spring Security configurations and components?
- Configure Spring Boot to use an external OTP service for two-factor authentication.
- Implement custom authentication filters to handle two-factor authentication.
- Use OAuth2 for authentication instead of two-factor authentication.
- Utilize Spring Security's built-in two-factor authentication support.
To implement Two-Factor Authentication in Spring Security, you would typically need to implement custom authentication filters to handle this process. Spring Security does provide support for two-factor authentication, but it often requires customizations based on specific requirements. OAuth2 is a different authentication mechanism and is not related to Two-Factor Authentication. Configuring Spring Boot to use an external OTP service is a specific approach, not a general method for Two-Factor Authentication.
