-                                        When initiating SMP, this is an alternative to the 'otr smp' command. The shared secret is provided as the answer to a specific question. The question is transmitted with the initial SMP packet and used to prompt the other party. If the protocol succeeds (i.e. they give the correct answer), the fingerprint will be trusted.

You must be confident that only they know the answer. If the protocol succeeds (i.e. they answer correctly), the fingerprint will be trusted. Note that the answer must be entered exactly, case and punctuation count!
