Hi Sergio González......I'm getting Error: redirect_uri_mismatch
The redirect URI in the request: http://localhost:8080/c/portal/google_login?cmd=token did not match a registered redirect URI.....I have followed README.md but could not add redirect URI to my application..there is no field to add redirectURI
Solved issue by registraring my application
APIs & auth>Registered App>RIGISTER APP
Simple but really useful plugin. Could be more configurable (like other login methods, through control panel).
