What about the part about forgetting which number it is? Maybe I'm just biased, having had the same number for the last 15 years? I know I had a few numbers when I was living in other countries and those are still written somewhere but of course no longer accessible or under my control.

Still though.... well I'm on both sides of this lol

I used to have the same number for 10 years, but then I moved to a different country, so now some of my 2FA is tied to that old number and changing it requires physical travel to regulated institution.
