stauthlib

This is a prototype for authentication in Streamlit. It supports all OIDC providers (e.g., Google, Microsoft etc.).

Usage

1. Clone this repo: git clone https://github.com/kajarenc/stauthlib
2. Install the requirements: pip install -r requirements.txt. Note that this will install a custom Streamlit wheel from this PR.
3. Run the Streamlit app: streamlit run app.py
4. Create a client ID and client secret from your OAuth provider. E.g. for Google, there's a good explanation here. Note that you have to provide the redirect URI to the provider, which is http://localhost:8501/oauth2callback.
5. Add the redirect URI (http://localhost:8501/oauth2callback), client ID, and client secret to .streamlit/secrets.toml. You can remove the code for providers you don't use.
6. Go to your app on http://localhost:8501 and click on your provider's login button. You should now be able to log in and then be redirected back to your app!

API

With the wheel file in this repo, you can use the following commands in your Python code:

• st.experimental_user shows you information about the user when logged in (e.g., their email, name, and avatar image). This information comes from the OAuth provider.
• st.experimental_user.login(provider="google") will send the user to the OAuth provider and let them log in. After login, they will be redirected to the app. Note that a user can only be signed in with one provider at a time, i.e. logging in with a different provider will log them out of the previous one.
• st.experimental_user.logout() will log out a signed-in user.
• st.experimental_user.is_authenticated checks whether the user is authenticated.

See app.py for a full example of how to use this code.
