Password Engineer
A modern UI presents this random password generator with selectable RNG, either multi-pendulum or barrel-o-letters, with 3D visualization. To contextualize the generation process, the physical models will include in configuration space, the many bodies dominating our gravitationally bounded part of the expanding universe, locally to Earth, if I can find a cheap way to geolocate the user. Engineer's default password candidate filter eliminates those with letter repetitions, which is for working comfort of the user's letter transposition process (noting or entering).
