PromptLink

Simplify user authentication and secure access from anywhere with temporary links.

PromptLink is a Python package that allows you to streamline user authentication and enable secure access to your application from anywhere. It provides a seamless way to generate temporary links for user authentication, without relying on specific web frameworks. A Google Cloud Function is set up to ensure a secure temporary link for authentication.

Key Features

• Easy and secure: Generate secure temporary links to enable easy secure access from anywhere.
• Versatile Integration: Works across various application types, not limited to web applications.

Installation

You can install PromptLink using pip:

pip install promptlink

Alternatively, if you are using Poetry (recommended), you can install it as follows:

poetry add promptlink

Usage

Here's a basic example of using PromptLink:

from promptlink import Authenticator


with Authenticator(send_link_callback=lambda l: print(f"URL: {l}")) as authenticator:
    # The code in this block is executed after the link has been accessed 
    # in order to avoid authentication timeouts
    print("Setting up authentication...")
    authenticator.authenticate(lambda s: s == "12345678")
    # Below statements will be reached after '12345678' was input on the webpage prompt
    print("Finished")

GCP permission requirements

The following permissions are needed for this library:

• Permissions to create Storage buckets and objects
• Permissions to set up a Pub/Sub topic and subscriptions
• Permissions to deploy a Cloud Function

The library will attempt to use the default service account. Any resources created will be named 'promptlink-' followed by a random UUID, so that collision with existing resources is extremely unlikely.
