What makes a password strong

Length matters most. Every extra character multiplies the guesses an attacker needs, which is why a long passphrase of random words beats a short password full of symbols. Avoid anything on common-password lists, names, dates and keyboard runs like qwerty, because attackers try those first.

The estimate here is deliberately simple: it measures the character pool and length, then cuts the score for the patterns crackers try first. Treat it as a guide, and use a different password for every site.
