PassBuff (Password Buffer) is an application which strengthens common or weak passwords by suggesting “buffs” as well as hints for improvement. The strength of the password, ranging from 1 to 7, is gauged using the zxcvbn library in addition to a natural language processing model based off of Kaggle’s Password Strength Classifier Dataset.
