I tried many different getpass style packages but they either didn't install properly or would't work. The code below has been adapted from getpass3. It requires the getch package and only runs under Python 3.

#/usr/bin/env python3

from getch import *
import sys

echo = '*'

def getpass(label):
    print(label, end='', flush=True)

    password = ''

    while True:
        inp = getch()

        if inp == '\n':
            break
        elif inp == '\003':
            raise KeyboardInterrupt
        elif inp == '\04':
            raise EOFError
        else:
            print(echo, end='', flush=True)
            password += inp

    print('')

    return password

print(getpass("Password: "))
