One Login for website and Chrome Extension

Hi Saif here, Im using auth0 API on my website also on Plugin. I want when someone login to the plugin, automatically login to the website and vice versa. is there any way I can authenticate users via token/sessionKey, not the user credentials? For example, User A login to I saved the response from auth0 to local storage so, the User automatically login next time but now in the Plugin same user click on the login button I send the token from local storage to auth0 for authentication rather than username and password. is there any way?
