Ask HN: Why aren't images used as passwords?
2 by poletopole | 1 comments on Hacker News.
We can all agree the state of password management on any platform isn't ideal, but some are better than others. Textual passwords are needed for some use cases obviously, but at large this isn't the case. With steganography or simple checksums alone I could easily see the possibilities that support the argument why images may be valid. Why would this not work in practice?
