 To refresh your tokens when using implicit flow you can use a silent refresh. This is a well-known solution that compensates the fact that implicit flow does not allow for issuing a refresh token. It uses a hidden iframe to get another token from the auth server. When the user is there still logged in (by using a cookie) it will respond without user interaction and provide new tokens.
