Ask HN: How do you change all your 2FA to new number?
Hey HN, is there a service that finds all the apps and sites you have 2FA with your current phone and lets you change it to a different number (or even better, a temporary number)?
I'll manually change all the ones I remember but sometimes there's the scarcely-used email address or account that you lose access to completely because of a forgotten 2FA switch.
There's gotta be a better way by now right?

- personjerry 5y agoAre these commonly accepted? I always use authenticator app where possible, but tbh a vast number of 2FA only allows cell phone.
