Dashboard Plugin modification due to user ID change

In an attempt to secure my wordpress site, I changed my own (the admin user) from User ID (with the Better WP Security Plugin), so now my WPMU Dev Dashboard is not showing up.
I read in a few other Q&As what code needs to be added to the wp-config.php file to make it visible again, but for that I need to know my user id.

Any tips on how I can find out what my USER Id is now?

Thank you
