Hi Angel, You will need to store your refreshToken in a secure place as this will allow you to automatically create new access tokens when the previous ones expire. Additionally, you may refer to the recommendation in this guide <https://developers.google.com/identity/protocols/OAuth2WebServer> for the web app flow, that you instead use client libraries when interacting with Google's OAuth2.0 endpoints as a security measure.
