The Invoice Auto Login addon allows you to include a new merge field in the invoice email templates that will automatically login the user and redirect them to the unpaid invoice. The key used in the URL is a randomly generated hash and automatically expires when the invoice is paid, cancelled or 20 days has passed since the key was generated.
