Prospects for Improving Password Selection
summary
Using prospect theory to frame a weak initial password as a loss relative to a stronger choice and prompting users with a popup to return causes about 25–26% of prompted users to pick stronger passwords, and the negative framing line shows overall stronger final passwords than neutral or positive framing. Adding a strength meter has no measurable effect, while of the 71 users who chose to return 71% successfully improve their password. Study uses mock accounts, limiting realism.
