This extension removes the active authentication key so that the WooCommerce ShipStation integration extension can generate a new key. Only use this if you’re intentionally removing the key for some reason, and are having trouble deleting woocommerce_shipstation_auth_key option from wp-admin/options.php

Reset ShipStation Authentication Key tool under WooCommerce > Tools (or WooCommerce > Status > Tools)Delete Key on the rightAuthentication Key field for the store with the newly generated key.
If you reset the authentication key, but don’t update the new key in ShipStation account, the integration between your store and ShipStation account will break.
