London railway station system passwords for the signal system of the control room at the Waterloo rail station in London were disclosed during a TV documentary.The documentary, starring Nick Hewer and Margaret Mountford, is available via YouTube here. El Reg flagged up the snafu to National Rail in the interests of encouraging a switch of passwords.
There are precedents for visual security slip-ups of this kind. Back in 2012 the UK's Ministry of Defence was obliged to reset user names and passwords following the publication of pictures of the Duke of Cambridge at work as a helicopter pilot on an RAF station.
The passwords are stucked to a monitor and are visible during a scene where the two business experts went into the control room at the rail station Waterloo in London.
Some of the pictures, released by St James's Palace, showed Prince William at work at RAF Valley but failed to redact sensitive login info, written on a bulletin boards in the background of shots taken at the RAF base in north Wales.
London Waterloo's signalling is not controlled from Waterloo itself and it doesn't use desktop computers as it's controlled from dedicated signalling panels.
