Getting a hidden password input

Use getpass.getpass():

from getpass import getpass
password = getpass()

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

Note that this function requires a proper terminal, so it can turn off echoing of typed characters – see “GetPassWarning: Can not control echo on the terminal” when running from IDLE for further details.

import getpass

pswd = getpass.getpass('Password:')

getpass works on Linux, Windows, and Mac.

Use getpass for this purpose.

getpass.getpass - Prompt the user for a password without echoing

This code will print an asterisk instead of every letter.

import sys
import msvcrt

passwor = ''
while True:
    x = msvcrt.getch()
    if x == '\r':
        break
    sys.stdout.write('*')
    passwor +=x

print '\n'+passwor

Updating on the answer of @Ahmed ALaa

# import msvcrt
import getch

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

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

msvcrt us only for windows, but getch from PyPI should work for both (I only tested with linux). You can also comment/uncomment the two lines to make it work for windows.

Here is my code based off the code offered by @Ahmed ALaa

Features:

Works for passwords up to 64 characters

Accepts backspace input

Outputs * character (DEC: 42 ; HEX: 0x2A) instead of the input character

Demerits:

Works on Windows only

The function secure_password_input() returns the password as a string when called. It accepts a Password Prompt string, which will be displayed to the user to type the password

def secure_password_input(prompt=''):
    p_s = ''
    proxy_string = [' '] * 64
    while True:
        sys.stdout.write('\x0D' + prompt + ''.join(proxy_string))
        c = msvcrt.getch()
        if c == b'\r':
            break
        elif c == b'\x08':
            p_s = p_s[:-1]
            proxy_string[len(p_s)] = " "
        else:
            proxy_string[len(p_s)] = "*"
            p_s += c.decode()

    sys.stdout.write('\n')
    return p_s
