Welcome to the discussion boards!
You can't directly use the Token Auth provider to bypass the login screen, as Kibana still requires a username and password to create the initial token. How are your users authenticating to your website? I have a couple of ideas for you:
If you're using a Single Sign-On solution such as SAML, AD/LDAP, or OpenID Connect, then you can take advantage of Kibana's SSO solutions to bypass the login screen.
Otherwise, you may want to consider putting a reverse-proxy (such as nginx) in front of Kibana which handles authentication on behalf of your users. An example of that can be found here: Auto-authenticating to iframe-embedded Kibana dashboard
