Human Factors
[Lead] FA (Flight Attendant) communicated after door closure that FO (First Officer) was an FFDO (Federal Flight Deck Officer); and for me to please communicate information with [the other] FAs. Due to a hectic taxi in which guests had to be repeatedly asked to sit down and fasten seatbelts; information slipped my mind.Communicate information immediately when received; additionally if there was a way to put a triangle by FFDO names in [our computer system] in order to communicate in the event of a busy boarding process; the information would be accessible.
Flight Attendant reported a failure to inform other flight attendants that the First Officer was an FFDO.
