title: Guidelines for a Password Strength Meter (Password checker) Design
body: <p>I have tried different types of Password Strength Meters or Password checkers, but all give me different results when I test the same Password, because each implements its own algorithm.</p>
  
  <p>Is there some official standard or guideline that can follow me to build my own Password Strength Meter.</p>
  
  <p>If there was no official standard, what features should a good Password Strength Meter check for?</p>
