The team of researchers, based in the CyLab Usable Privacy and Security (CUPS) Lab, asked 165 online participants — 51 percent male, 49 percent female from 33 U.S. states ranging from 18 to 66 years of age — to rate the comparative security and memorability of 25 juxtaposed password pairs. In addition, participants were asked to articulate how they would expect attackers to try to guess their passwords.
“As companies are designing tools that help people make passwords, they should not only be giving users real-time feedback on the strength of their passwords, but also be providing data-driven feedback on how to make them stronger,” Ur said.
The team will incorporate these findings into an open-source password feedback tool, which they aim to release before the end of the year.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
