How Can I Securely Get Password Input in Python?

Secure Password Input in Python

In Linux systems, commands like Sudo require password input without displaying the characters being typed. This is a crucial security measure to protect sensitive information. We can replicate this functionality in Python using the getpass module.

The getpass.getpass() function provides a secure method for obtaining a password from the user without echoing it to the terminal. This is ideal for scripts that require sensitive information, such as passwords or credentials.

To use this function, simply import the getpass module and call getpass.getpass(). The function will prompt the user for a password using the default text "Password: ". You can optionally provide a custom prompt as a parameter.

from getpass import getpass
password = getpass("Enter password: ")

The entered password will be stored in the password variable as a string. Since the characters are not echoed during input, the password is securely hidden from view.

It's important to note that getpass.getpass() requires a proper terminal that can disable echoing. If you encounter any issues while running the script, refer to the GetPassWarning documentation for further troubleshooting.
