Don't do that. Create a new account with the email address you have access to.
Apps require you to sign in again all the time, and send a verification code to your e-mail to do so. Changing locations is, yes, a reason to require sign in.
Sorry, but that one's on you.
Because in the context of signing in, its role is that of a user ID.
Ticketmaster spams that address constantly. It's a valid email address, to be sure, but they've trained me over the years never to look at it. They certainly didn't do any multi-factor authentication when I bought the tickets, only when I was preparing to use them (despite having accessed them on that very device two days earlier).
This is the bane of my existence. I manually copy/paste/delete a half-dozen codes from my email/SMS every single day.
If I was ruler, I'd mandate every one of these switch to TOTP 2FA and outright ban email verification other than for password resets.
What? TicketMaster is the only app I use that does this. Probably because it's too hard for end-users to get rid of it. If some Telegram or some food delivery app or something tried to periodically re-prompt me to log in because I went outside my house or whatever, it would get uninstalled and replaced with something that didn't.
