update the credentials field in the Authenticate object

[Pol-dea]

I have been using this module for a year and find it to be an excellent job.

For my application I need to edit (as admin) the roles of other users (members, guests..) in a specific page and I was able to load the config file and update it.
what I can't do is update the credentials and roles inside the Authenticate object, so that I can keep this information updated after logout for example.

So far I have initialized the object by passing the path of the config file as the credentials parameter, because it is very convenient to have the module handle all the changes in the file itself.
Since I have this requirement, the only way I can solve this problem is to pass the credentials list to the object and manually modify it every time I interact with a stauth widget? Or is there a better way?

Hi @Pol-dea, thanks for reaching out! Can you please elaborate, I'm not sure I quite understand what you mean when you what I can't do is update the credentials and roles inside the Authenticate object, so that I can keep this information updated after logout for example.

Let me try to explain myself better. What i am trying to do is to create a page where it is possible to edit the roles of other users and delete users. I have been able to read the config file and user credentials, make the necessary changes, and update the config file.
My problem is how to update the changes also in the Authenticate class, because the credentials dict stored in my authenticator object is still the old one, and will replace the one I updated at the next interaction with any class widget.

First thing I do at the start of every page of my app is to call this function

def auth_init():
    if 'authenticator' not in st.session_state:
        config = read_config_file("config.yaml")
        if not config['credentials'].get('hashed', False):
            config['credentials'] = stauth.Hasher.hash_passwords(config['credentials'])
            config['credentials']['hashed'] = True
            write_config_file("config.yaml", config)
        st.session_state['authenticator'] = stauth.Authenticate(
            'config.yaml',
            config['cookie']['name'],
            config['cookie']['key'],
            config['cookie']['expiry_days'],
            auto_hash=False,
        )

I tried to recreate the object after my changes at the config file, but it gives my an error (only one instance of the Authenticate class can exist at a time) so I don't know how to do it.
