Selected Answer: C

One possible cause of the issue is time drift between FortiAuthenticator and hardware tokens. Time drift occurs when the internal clocks of FortiAuthenticator and hardware tokens are not synchronized. This can result in mismatched one-time passwords (OTPs) generated by the hardware tokens and expected by FortiAuthenticator. To prevent this issue, FortiAuthenticator provides a time drift tolerance option that allows a certain number of seconds of difference between the clocks.
