Compromising one of these passwords does not at all mean that all the other passwords are compromised. You can't figure out the original master password from a hashed, compromised password.
- thirsteh 12y agoYes, you can. To understand why, compare: This: 'facebook' + 'mypassword' 'twitter' + 'mypassword' 'foursquare' + 'mypassword' Password manager with unique passwords: 'mSX32ZyKZXptY3E' '33RiKbc3n6sA6IY' '4kGzFtWDd0rnti6' All I have to do is figure out what you named the site that I compromised, then do exactly what I'd usually do to recover your password, and, voila, I can now access all sites you use it for. Compare this to the password manager example where each password has been generated at random--one password communicates no information whatsoever about the other.
- aba_sababa 12y agoOk, so you know that "facebook" is part of the original hash. Not following how you can also derive "mypassword" from it. If you have a good strong master password, rainbow tables won't be able to crack the hash.
