Add password strength check (#983)
* Add password strength check * Delete time.sleep and log, use the select class instead * Ignore W503 in flake8 * Solve some problems of the password strength check algorithm Part of the code was written by @phisch. This code tries to measure the strength of the user's password and suggests that the password is weak. * rename function * Restore the flake8 configuration file to its previous state
