Moped Mirrors

If its the UK, then No, there is not!
You will see a large number of old scooters (Vespa ECT) to walk without mirrors! and elsewhere if it is not equipped with indicators that you do not need it either! (On the other hand, if they were installed, then they must work!)

depends what year it is, old moped in the 70s and before mirrors were DONT need a password. MOT decisions apply only to the date on which they were implemented. Thus, in the 1980s (84 I think) all of the bikes built at that date or from the United Kingdom have approved exhaust (BS kite marks) before that date are exhaust-noise's Word, if n is not too strong word to testers ears, then pass!.
You would need to know if it is required by asking your inspection station, as I do not have any information that could help
