It's not obvious that the picture is related to the password field. Had I not had the preface that this helped visualize the password, I probably would have thought it was a gif or something.
Regardless, it's a cool effect.
Like the idea, but would make more sense to reverse the effect.
Yeah, I thought it was backwards as well.
I was going back and forth on this too. On one hand, the clarity once you’ve reached the highest strength level is an apparent stopping point, but it does make more intuitive sense to obfuscate the image as the password becomes more secure.
Super cool concept. Ultimately, though, the idea that people are manually creating passwords and not using something like 1password gives me so much anxiety.
They have a link in the corner to a demo that does it in reverse.
