Service to login and get API tokens?

I'm building a micro SaaS where I need to execute some Google API and get user data. For it, I need to auth user with google and get auth token to use with API request.

I know how to do it, but I do not want to build my solution and then manage auth tokens, refresh tokens, scopes, and security.

Are some services that can help me? With integration to Webflow?

Requirements:

• Login user with Google, Apple ID
• Store user auth token
• Refresh tokens automatically
• Retrieve tokens to make a custom API request to Google/Apple
