Description: First-factor authentication is the initial step in the identity verification process, typically involving the use of a password or PIN. This method relies on something the user knows, meaning that security depends on the strength of this information. First-factor authentication is fundamental in identity and access management, as it establishes the foundation for accessing sensitive systems and data. Although it is a straightforward and widely used method, its effectiveness can be compromised if passwords are weak or subject to attacks such as phishing. Therefore, it is crucial for users to choose strong passwords and change them regularly. Despite its limitations, first-factor authentication remains a common practice across various platforms due to its ease of implementation and use. However, in an environment where cyber threats are becoming increasingly sophisticated, many organizations are beginning to adopt more advanced authentication methods, such as multi-factor authentication, which combines the first factor with other verification methods to enhance security.
