st.logout

Logout the current user.

This command removes the user's information from st.user, deletes their identity cookie, and redirects them back to your app's home page. This creates a new session.

If the user has multiple sessions open in the same browser, st.user will not be cleared in any other session. st.user only reads from the identity cookie at the start of a session. After a session is running, you must call st.login() or st.logout() within that session to update st.user.

Note

This does not log the user out of their underlying account from the identity provider.

Function signature[source]

st.logout()

Example

.streamlit/secrets.toml:

[auth]
redirect_uri = "http://localhost:8501/oauth2callback"
cookie_secret = "xxx"
client_id = "xxx"
client_secret = "xxx"
server_metadata_url = "https://accounts.google.com/.well-known/openid-configuration"  # fmt: skip

Your app code:

import streamlit as st

if not st.user.is_logged_in:
    if st.button("Log in"):
        st.login()
else:
    if st.button("Log out"):
        st.logout()
    st.write(f"Hello, {st.user.name}!")
