single methods of authentication can be compromised more easily than MFA. MFA, or multi-factor authentication, is a security process that requires users to provide two or more factors to verify their identity and access resources. MFA reduces the risk of unauthorized access by making it harder for attackers to compromise all the factors needed, especially if they are different in nature, such as something you know (password), something you have (token), and something you are (biometric).
To understand the concept of MFA and why it is important for authentication security, you can refer to the following sections of the source book:
* Section 1.1.1: Describe the concepts of identity and access management
* Section 1.1.1.1: Describe the concepts of identity principles
* Section 1.1.1.2: Describe the concepts of authentication
* Section 1.1.1.3: Describe the concepts of authorization
* Section 1.1.1.4: Describe the concepts of accounting
* Section 1.1.1.5: Describe the concepts of identity stores
* Section 1.1.1.6: Describe the concepts of MFA
