Salesforce Certified Identity and Access Management Practice

A "Security Token" in Salesforce plays a critical role in verifying user identity, especially during API calls or when accessing Salesforce from untrusted networks. It adds an extra layer of security by functioning as a unique code that works in conjunction with the user's password. When a user attempts to log in to Salesforce from a network that the system does not recognize, such as a public Wi-Fi connection, the security token ensures that the access attempt is safe and authorized. This mechanism is particularly important in safeguarding sensitive data and preventing unauthorized access. Users must append their security token to their password when they log in through the API, thus confirming that they are legitimate users attempting to access their accounts, even in less secure environments. In contrast, other options do not accurately represent the role of a security token. While backup codes for password recovery or data encryption methods are important, they do not relate to the functionality of a security token. Similarly, identifying subscriptions is unrelated to user authentication and access management, which is the primary purpose of the security token within Salesforce.
