We'll use this to match your answers on this survey to the answers on all the others without de-anonymizing you. Go to
https://catonmat.net/tools/generate-random-passwords, make it generate some for you, and choose your favorite. It should be a long random string like "4rsWsGnnkxAL7QKF". Paste it here, then save it so you can include it on the other surveys. Please keep this user ID saved - I might ask for it again on future ACX surveys so we can chain them together!
