Cannot instantiate authenticator object in multiple pages: DuplicatedWidgetId

[mattiatantardini]

I'm following the documentation at steps 1 and 2, which states that one needs to recreate the Authenticator object and call the login method on each page of a multipage app.

I'm testing the functionality but cannot recreate the object in a different page. The exception is the following:

DuplicateWidgetID: There are multiple widgets with the same key='init'.

To fix this, please make sure that the key argument is unique for each widget you create.

Traceback:

I looked at the source code and it seems to me that there is no way to pass an explicit key to the CookieManager instantiated within the Authenticate object, which results for the CookieManager to always use the default init key.

My code follows.

app.py

import yaml
from yaml.loader import SafeLoader

import streamlit as st
import streamlit_authenticator as stauth
from streamlit_option_menu import option_menu

from app.pages.anagrafica import anagrafica_page

if __name__ == "__main__":

    with st.sidebar:
        st.title("My app")

    with open('./settings/users.yaml') as file:
        config = yaml.load(file, Loader=SafeLoader)

    authenticator = stauth.Authenticate(
        config['credentials'],
        config['cookie']['name'],
        config['cookie']['key'],
        config['cookie']['expiry_days'],
        config['pre-authorized']
    )

    authenticator.login()

    if st.session_state["authentication_status"]:
        with st.sidebar:
            # authenticator.logout()  
            st.write(f'Welcome *{st.session_state["name"]}*')

            page = option_menu(
                menu_title="Menù",
                options=["Anagrafica", "Tessere", "Scontrini", "Prodotti"],
                icons=["people-fill", "card-text", "receipt", "tag-fill"],
            )

        if page == "Anagrafica":
            anagrafica_page()

    elif st.session_state["authentication_status"] is False:
        st.error('Username/password is incorrect')
    elif st.session_state["authentication_status"] is None:
        st.warning('Please enter your username and password')

app.pages.anagrafica.py

import yaml
from yaml.loader import SafeLoader

import streamlit as st
import streamlit_authenticator as stauth

def anagrafica_page():

    with open('./settings/users.yaml') as file:
        config = yaml.load(file, Loader=SafeLoader)

    authenticator = stauth.Authenticate(
        config['credentials'],
        config['cookie']['name'],
        config['cookie']['key'],
        config['cookie']['expiry_days'],
        config['pre-authorized'],
        # key="anagrafica-auth"
    )

    authenticator.login()

    st.title("Anagrafica")

Environment:

• python 3.11
• streamlit 1.33.0
• extra-streamlit-components 0.1.71
• streamlit-option-menu 0.3.12

Is there some sort of bug or am I missing something?

I think that it might be the path you're in. It could also be that there might be an init file where there shouldn't be.

Dear all, this issue will be resolved in the next release.
