The only requirement for this is the random module of python that we will be using to generate random characters every time (I will explain it later when we use it in our program). It's the final and simplest step, display the generated password to the user.Now that we have taken the user's input we would generate a random password (combination of numbers, symbols and alphabets) of the given length.So, we will ask the user to enter the length of the password. First of all we want to make this dynamic (something that is not fixed or pre-defined) so that the user can generate a password of any length.Let's first see what do we want as our end result so that we can start building our password generator. So, now as we have understood the need for a password generator let's start building our own. But nonetheless, you should make one because it would really help to learn some basic concepts of Python and you can share it with your friends or family who might need it. But if you are someone like me, who always struggles to think of a strong password, then this would be helpful for you.

Yeah, you probably won't need a password generator if you are great at creating new and strong passwords for your accounts on different websites. Well as the name suggests it is an application/program that will generate a new, strong and random password every time. Otherwise, let's move on and build our password generator. In my previous article, I've gone through how Python works under the hood, if you haven't read that and want to read it you can check it out here. In this article, I will be showing how can we make our own password generator using Python. Using random.choice would allow this to work on non-posix systems.īy constraining the password to never contain consecutive characters from the same set you are limiting the complexity of the password, perhaps not by much, but you would be making someone's life easier at some point reducing the search space for a brute force attack.īut, if you did want to do this then just picking the next character's set at random out of the other character sets would be more efficient. from random import choiceĪ_char = choice('abcdefghijklmnopqrstuvwxyz') I'm not sure why you'd make repeated calls to 'urandom' and check that the result is in your target character set instead of choosing a random character from the set.

You've missed out the import statement: from os import urandom
