This password is not the best one though so our program will make the passwords completely random. For example if my favorite animal was a jaguar and I chose jaguar as a keyword, we could use this to make a password like “23#jaguarsrock!”. For this question, if the user says “yes” we ask them what their keyword is. The code below tells the user that the computer will generate a random password, and then uses the input function to ask them if they would like a keyword. Embedding a keyword in your password Now we write the main driver routine. We also randomize the choice of lowercase or uppercase and transform the character appropriately. For the letters, we create a string containing all letters and then select a random integer from 0 to 25 to decide on the index into the string. To obtain a random number we use the same function, i.e., randint, to obtain a number from zero to nine inclusive. If we obtain 1, we will select a random number if we obtain 2, we will select a random letter and if we obtain 3, we will select a random character. We use the random.randint() function for this purpose. Here is the full function To decide what type of character to generate we choose a random number from 1 to 3 (inclusive). This function (and everything below) makes heavy use of the random package in Python. The below code defines a function that returns a random character, which could be a letter (uppercase, lowercase), a number, or a special character. Choosing a single random character To begin, let us make a function that chooses a single random character for our program. In the first run we choose to have a password keyphrase (here, “kodeclik”) and in the second we do not have a keyphrase. Sample runs Here are two runs with our Python program that we present below. For instance “kodeclik” is not a good password choice but “Y!*kodeclik9Bx” could be. There could be some memorable keywords inside the password but in overall it should not be an obvious choice. Further, the letters should be of different cases, ideally. Aren’t you tired of thinking up new passwords for every application or website? Wouldn’t it be nice to create your own personal password generator? In this blogpost we show you how! What makes a good password? A good password should be difficult to guess and it should have a mix of different types of characters: letters, numbers, special characters.
