- yencabulator 3y agoOh yes, that could be it! Employer made me run Windows in a VM to read corporate email. My memory doesn't match videos I can find online of it, but that could be version differences.

(IIRC the number of dots in the password field was also generated, so it didn't necessarily match the number of chars) The image was essentially a simple checksum. Each user would eventually memorise which icon was "theirs".
