I am trying to get the customers Access Token while they are logged in to our
Magento 2.1.8 site while using a custom module I am developing.
I have been following the official Magento 2 tutorials to do this and it says that to get the token I must send the user's
password to the appropriate API endpoint. When the Access Token is required, the user is already signed in.
How do I get the logged in users Customers Access Token without using their Username and Password?
