Authenticating a user from saved credentials

[Jonovono]

Is this possible to do?

I know in the nodejs one it seems possible?

OAuth.auth('provider', req.session, {
    credentials: credentials
})
  .then(function (request_object) {
     // Here request_object has been rebuilt from the credentials object
    // If the credentials are expired and contain a refresh token,
    // the auth method automatically refresh them.
   });

Wondering if you can do this in browser JS.

Thanks
