@Egos to allow users to view your private app without using “Continue with Google” or login via GitHub, you can simply have them login via “sign in with email” – this feature will send an email to them with a link that they can use to magically sign in without Google or GitHub. Check out the docs for this here.
Again, public apps are accessible without logging in. I should also mention that Streamlit Community Cloud serves as a free resource for people getting started with Streamlit to deploy a few apps – we don’t recommend Streamlit Community Cloud as an enterprise business solution, which it sounds like you might be looking for. We do have a great community wiki on other deployment options.
