Obtaining a password input that is hidden


When you try some Sudo stuff in Linux, it prompts you to input the password, but nothing appears in the terminal window as you type (the password isn’t shown)?

Is it possible to achieve that in Python? I’m working on a script that involves a lot of private information, and I’d like to keep it hidden as I type it.

In other words, I’d like to retrieve the user’s password without having to reveal it.

Use getpass.getpass():

from getpass import getpass
password = getpass()

An optional prompt can be passed as parameter; the default is “Password: “.

This function requires a good terminal to turn off echoing of typed text — for more information, see “GetPassWarning: Cannot control echo on the terminal” when running from IDLE.

import getpass

pswd = getpass.getpass('Password:')

getpass is compatible with Linux, Windows, and Mac.

Getpass can be used for this.

Instead of each letter, this code will print an asterisk.

import sys
import msvcrt

passwor = ''
while True:
    x = msvcrt.getch()
    if x == '\r':
    passwor +=x

print '\n'+passwor

@Ahmed ALaa’s response has been updated.

# import msvcrt
import getch

def getPass():
    passwor = ''
    while True:
        x = getch.getch()
        # x = msvcrt.getch().decode("utf-8")
        if x == '\r' or x == '\n':
        print('*', end='', flush=True)
        passwor +=x
    return passwor

print("\nout=", getPass())

msvcrt is exclusively for Windows, however PyPI’s getch should work for both (I only tested with linux). To make it work for Windows, you simply comment or uncomment the two lines.
