Streamlit Login/ Sign Up Library

The streamlit_login_auth_ui library is meant for streamlit application developers. It lets you connect your streamlit application to a pre-built and secure Login/ Sign-Up page.

You can customize specific parts of the page without any hassle!

The library grants users an option to reset their password, users can click on Forgot Password? after which an Email is triggered containing a temporary, randomly generated password.

The library also sets encrypted cookies to remember and automatically authenticate the users without password.
The users can logout using the Logout button.

Installation

pip install streamlit-login-auth-ui

How to implement the library?

To import the library, just paste this at the starting of the code:

from streamlit_login_auth_ui.widgets import __login__

All you need to do is create an object for the __login__ class and pass the following parameters:

1. auth_token : The unique authorization token received from - https://www.courier.com/email-api/
2. company_name : This is the name of the person/ organization which will send the password reset email.
3. width : Width of the animation on the login page.
4. height : Height of the animation on the login page.
5. logout_button_name : The logout button name.
6. hide_menu_bool : Pass True if the streamlit menu should be hidden.
7. hide_footer_bool : Pass True if the 'made with streamlit' footer should be hidden.
8. lottie_url : The lottie animation you would like to use on the login page. Explore animations at - https://lottiefiles.com/featured

Mandatory Arguments:

• auth_token
• company_name
• width
• height

Non Mandatory Arguments:

• logout_button_name [default = 'Logout']
• hide_menu_bool [default = False]
• hide_footer_bool [default = False]
• lottie_url [default = https://assets8.lottiefiles.com/packages/lf20_ktwnwv5m.json]

After doing that, just call the build_login_ui() function using the object you just created and store the return value in a variable.

Example:

import streamlit as st
from streamlit_login_auth_ui.widgets import __login__

__login__obj = __login__(auth_token = "courier_auth_token", 
                    company_name = "Shims",
                    width = 200, height = 250, 
                    logout_button_name = 'Logout', hide_menu_bool = False, 
                    hide_footer_bool = False, 
                    lottie_url = 'https://assets2.lottiefiles.com/packages/lf20_jcikwtux.json')

LOGGED_IN = __login__obj.build_login_ui()

if LOGGED_IN == True:

    st.markown("Your Streamlit Application Begins here!")

That's it! The library handles the rest.
Just make sure you call/ build your application indented under if st.session_state['LOGGED_IN'] == True:, this guarantees that your application runs only after the user is securely logged in.
