We could build a passphrase generator like we did with simple passwords above, but why bother when there's library available for this. If it's just an initial, temporary password or short-lived token then it's fine, but if user should is it for longer, then it's more appropriate to use passphrase instead. The passwords generated using above code will be strong, but very hard to remember. Password = ''.join(secrets.choice(alphabet) for i in range(length)) # Choose wide set of characters, but consider what your system can handleĪlphabet = string.ascii_letters + string.digits + string.punctuation There isn't any library for generating passwords, but implementing it isn't difficult: For example if you want to set initial password that gets changed upon first login. Sometimes it might be preferable to generate a password rather than prompt user for one. Python will try to warn you about that, so just read warnings in command line. Be aware though that not every system supports hiding of passwords. Getpass is a very simple package that allows you to prompt user for password as well as get their username by extracting current user's login name. You could use input(), but that would show the password in terminal, to avoid that you should use getpass instead: Let's start simple - you have basic Python application with command line interface. So, in this article we will explore Python libraries, tools and concepts that will help as with exactly that! Prompting For Password Keeping these security elements safe includes, generating them, verifying them, storing them securely and protecting them from adversaries. You might not be security expert, but you should know how to deal with all these passwords and credentials securely to keep your application users' credentials and data protected as well as your own API keys and various token. Almost every application requires some form of authentication, password handling or use of secure credentials such as API keys.
