The plugin sends two different types of emails.
1. The first one is sent when you choose the Classic password recovery mode, and it’s the standard WooCommerce password reset email. You can customize it from WooCommerce > Settings > Emails > Reset password.
2. The plugin includes a new email that will be sent if you choose the password reset with Code mode. To customize this email, please, go to WooCommerce > Settings > Emails > Reset password authentication code.
