Maybe it's just that people around me travel more. But I would still expect anyone here to know about passport
UK was in the EU for the most part of my adulthood, so I didn't need a passport (I'm from Germany).
To enter, you didn't need a passport, but for most flights you did for the last few years. The airlines stopped accepting any I'd and required a passport. UK was never in Schengen but was in free movement, being part of EU.
Ireland is still not in Schengen as there is "borderless" travel between Ireland and northern Ireland.
