-### OAuth2 Standar Flow:
-
-1. **User** clicks button "Login with Google" on your platform `xorismesiti.gr`
-2. **Authorization Request**: Button redirects user to Google's authorization endpoint `accounts.google.com/o/oauth2`
-3. **User Login and Consent**: User login to Google and grants permissions.
-4. **Authorization Code Response**: Google redirects user back to your app `xorismesiti.gr/callback` with an authorization `code`.
-5. **Access Token Request**: App exchanges the authorization `code` for an `access_token`.
-6. **Access Protected Resources**: App uses the `access_token` to fetch the user's Google profile and email from `googleapis.com/oauth2`
-7. **Token Refresh** (Optional): If the `access_token` expires, app uses the `refresh token` to get a new `access_token`.

-### OAuth2 Frontend/Backend Flow:
-
-**Frontend**
-1. **Redirect** the user to Google's OAuth authorization endpoint `accounts.google.com/o/oauth2`
-2. **Get** the authorization `code` after Google redirects back to the frontend `xorismesiti.gr/callback`
-3. **Send** the authorization `code` to the backend for `token` exchange.
-
-**Backend**
-1. **exchange** the authorization `code` for an `access_token` and `refresh token`
-2. **fetch** user profile data from from `googleapis.com/oauth2` using the `access_token`
-3. **Store** the `tokens` securely in session (front) or a database (back)
-4. **Refresh** the `access_token` if it expires

-# 1. [Frontend] Request Authorization code
-
-1. A button "Login with Google" redirects the user to the Google's authorization endpoint `accounts.google.com/o/oauth2/v2/auth`
-2. After the redirection, the user will log in to Google and grant permissions (if they haven’t already).
-3. Google will redirect the user back to your redirect_uri `https://xorismesiti.gr/callback` with an authorization code `?code=`
