What is the function of FortiToken in authentication processes?

FortiToken plays a crucial role in enhancing security through two-factor authentication (2FA) by generating one-time passwords (OTPs). This adds an additional layer of protection beyond the standard username and password combination. When a user attempts to log in, FortiToken generates a unique OTP based on a time-synchronized algorithm or counter, which the user must then provide alongside their regular credentials.

This method significantly reduces the risk of unauthorized access since even if an attacker obtains the user's password, they would still need the OTP generated by FortiToken to successfully log in. By implementing FortiToken in the authentication process, organizations can better protect sensitive resources against a range of threats, including phishing attacks and credential theft.

The other options describe functions that are not aligned with the primary purpose of FortiToken. It does not store user credentials or verify emails; rather, it focuses on the secure generation of OTPs for 2FA. Additionally, while encryption is essential for securing data, it falls outside the scope of what FortiToken specifically offers in terms of functionality.
