Hello, I am trying to implement silent authentication using the auth0-spa-js library. The client application in Auth0 is a regular web application where the the “Token Endpoint Authentication Method” property is set to POST. I am unable to retrieve access tokens when “Token Endpoint Authentication Method” is set to POST but it works if I change it to None. Is this a requirement to allow silent authentication? ---

Hi @sreeram.jayan , That’s correct, for silent authentication, authorize endpoint equal to none. ---
