🚨 *IMPORTANT* 🚨 Shortly after releasing the video, the streamlit-authenticator package got updated. The new version is incompatible with the syntax I have shown in the video.

Hi Sven, I tried by myself. It worked

[@GidonLoewenberg]

Thanks for the tutorial (and the others too!). Would you be able to do an update for the new syntax? The 0.1.5 version has a bug where the username is case sensitive. This has been resolved in 0.2.1 and I would like to use it but can't figure out how to implement it correctly.

On logout I want the sidebar to be removed and take me back to the login page. after logout that only happens if I manually F5 the app then the sidebar is removed.

Great video! What if, I have 5 different pages inside my app for 5 different users. Is there a way I can create a login page where user 1 enters his credentials and see HIS dashboard and not the other 4?

[@CodingIsFun]

Thank you for watching. This seems feasible using the Streamlit Authenticator package. Please refer to the documentation: github.com/mkhorasani/Streamlit-Authenticator. For example, you could define various roles and add them to your database when someone registers. Within your Streamlit app, you would then need to check if the respective user has the required role to access the app. Happy Coding!

However, when the application is deployed, the GitHub repository link is displayed at the top of the Streamlit app. This allows users to access the repository, retrieve the '.pkl' file, and potentially use it to access the application.

I have a streamlit_autheticator problem, could anyone help me? KeyError: 'usernames'

[@CodingIsFun]

Shortly after releasing the video, the streamlit-authenticator package got updated. The new version is incompatible with the syntax I have shown in the video. If you want to follow along with the video, please use version 0.1.5 : pip install streamlit-authenticator==0.1.5

[@TharushikaHettiarachchi]

If you got an error as 'cannot import name 'path' from 'pathlib'', then change the following code lines # from pathlib import path to import pathlib and #file_path = path(__file__).parent / 'hashed_pw.pkl' to file_path = pathlib.Path(__file__).parent / 'hashed_pw.pkl'

[@CodingIsFun]

Pathlib is a core Python module available in Python 3.4 and above. To import it ensue to use a capital letter (as shown in the video): from pathlib import Path

[@Master_of_Chess_Shorts]

the secret key should be read from an environment variable not hardcoded

[@CodingIsFun]

Which secret key are you referring to? I mentioned that you could store the usernames and hashed passwords in a database (at 6:23 min in the video). In fact, I also created a tutorial on that.

[@Master_of_Chess_Shorts]

@@CodingIsFun at 3:43, what you refer as a "random key" is used to encrypt the cookie data so the session cannot be tampered. You should set it as an environment variable, read the key from the environment variable in your code. It's a small point and your video is great, this is just additional security and best practice so that viewers are aware of this point. Authentification could be a risky business in certain contexts.

thank you for the video very useful but it works just with streamlit-authenticator==0.1.5

I cannot replicate this error. Everything works as expected when I clone the Github repo and run the project with the version specified in the requirements.txt file.

@@CodingIsFun the same error with me Authenticate.__init__() got multiple values for argument 'cookie_expiry_days'. I believe the signature was different from method Authenticate(credentials: dict, cookie_name: str, key: str, cookie_expiry_days: int = 30, preauthorized: list = None)
