The imitation may be someone your user trusts.
Consider a message that appears to come from a bank, a physician, an executive or a public agency. The person behind the account may be real; the party asking them to act may be the imitation.
The question changes from “Is this really our user?” to “How does our user know it is really us?” FDA answers at the authentication interaction: the enrolled app verifies the authentication server and the person checks the request. It provides a basis for service verification when a convincing appearance is not enough.
