@mattblaze You can apply online, per https://www.gov.uk/guidance/apply-for-an-electronic-travel-authorisation-eta, so that the foreign government can capture all of the information any other website can collect about you, plant cookies, serve up tracking pixels, and more. (No, I don't know if they're doing any of that; I don't expect to be visiting the UK for several months.)
