  • the best password is no password at I doing this right? 🙂

  • Perhaps it's a moot point... no matter how unbreakable your password, you are likely to change it is a site is breached and credentials stolen - regardless of whether the attacker was able to crack your password over the list.

    So to make that something tangible, are we protecting a password against a targeted credential attack (i.e. someone specifically wants MY details), or from large scale breaches (in which case you are more likely to change regardless of password/passphrase strength).

    If it is the latter, then we get into areas of "did I know a site I frequent was breached"... etc which password managers typically do a good job of keeping track of.
