WordPress doesn’t recognise my email address and I’m missing the wp-config file in PHPmyadmin cPanel to make alterations

Google authentication sounds like the least of your worries.

wp-config.php lives in the public_html folder of your website, not in SQL database.

Assuming everything else is configured correctly, then you will simply need to put your SQL info into wp-config.php and then go to your main website url via the browser

      If wp-config.php doesn’t exist in /public_html folder, then look for wp-config-sample.php and rename it to wp-config.php

The last issue you’re encountering with the email address and user id is rather surprising if you’re generating a database connection error…
