Bad passwords and the NIST guidelines

Almost every web service you join will require you to come up with a password. But what makes a good password? In June 2017 the National Institute of Standards and Technology (NIST) published publication 800-63B titled Digital Identity Guidelines: Authentication and Lifecycle Management. This publication doesn't tell you what is a good password, but it does have specific rules for what is a bad password.

In this project, you will take a list of user passwords and, using publication 800-63B, you will write code that automatically detects and flags the bad passwords.

To complete this project, you need to know how to manipulate strings in pandas DataFrames and be familiar with regular expressions. Before starting this project we recommend that you have completed the following courses:

• Cleaning Data in Python
• Natural Language Processing Fundamentals in Python
