I broke down and bought a prepaid SIM and a small dumb phone which I use solely for 2FA. Its about the size as old-school 2FA systems like crypto cards. My original motivation in getting it was my wife was always taking my real phone to get security codes for some shared accounts (on sites that don't have an option for linked accounts). But I also like that it provides small OPSEC improvements over using my real telephone number.
