getpass alternative with masking, Spyder support and additional features
Project description
Maskpass
Maskpass is a Python library like getpass but with advanced features like masking and reveal/un-reveal.
It also works in Spyder IDE
Installation
Use the package manager pip to install maskpass.
pip install maskpass
It is currently recommended to enforce a version if you have plans to use it in a project, since backward incompatible changes may occur.
Usage
This module contains functions askpass() and advpass()
askpass() uses msvcrt.getch() in windows and altenatives in *nix OS, but it doesn't work in Spyder.
import maskpass
password = maskpass.askpass()
The function returns the entered password in string format
Accepts 2 optional arguments prompt and mask.
Default for prompt is Enter password:
. Default for mask is *
.
Use mask=""
for not echoing anything into the terminal. (Like entering sudo passwords in *nix)
Using advpass()
advpass() uses pynput to get the password, and it works in Spyder too!
import maskpass
password = maskpass.advpass()
The function returns the entered password in string format.
Accepts 4 optional arguments prompt, mask, ide and suppress.
-
prompt is the string to be printed. Default for prompt is
Enter password:
. -
mask is the masking character to be used, can be an empty string
""
, single or multi length character. Default for mask is*
. -
ide expects a bool, it is for overriding IDE check, and has default False. Usually there is no need to change this, since it's automatically checked whether it's running on IDE or terminal. Default is
False
. -
suppress expects a bool, is used only in Spyder/QTConsole. Setting this to True prevents the input from being passed to the rest of the system. See pynput documentation for more info. This prevents the Spyder console from jumping down when spacebar is pressed. Default is
True
.
advpass()
also has a revealing feature which will toggle the visibility of the entered password when Left CTRL
is pressed. Press it again to change back the visibility.
Note: Only works with advpass()
and needs pynput
Exceptions and other returns
In both askpass and advpass, pressing Ctrl+C
raise the usual KeyboardInterrupt
.
Also, pressing Escape
in both functions stops the input and returns an empty string ""
.

Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
Issues
There is an issue in Spyder where pressing and holding the backspace key yields unpredictable result. This only happens when the key is held down and only in Spyder. Only workaround right now is to backspace letter by letter and not hold it down.
Holding down backspace in advpass in Spyder
Currently I have only tested it in Windows 10, Manjaro and Parrot, so I'm not sure it works in macOS.
This will not work in Jupyter Notebook correctly. Haven't tested it in PyCharm yet, so it might work.
Tips
In some platforms, namely Termux in Android, maskpass does not get installed because pynput cannot install in that. In those platform (or in cases where you don't need advpass), if you would like to use only askpass, just copy both /maskpass/input_methods/without_pynput.py
and /maskpass/input_methods/cross_getch
to your desired location and you can use askpass using from without_pynput import askpass
