I've been lucky enough to have my phone number for the past decade and all of the services I use have already authenticated that number. When I moved to Europe earlier this year, I ported my number from BIG_NAME_CARRIER to Google Voice and so far everything has been fine. That said, I'm still vigilant for alternative login options when I see them because I assume sooner than later, some company will audit all customer numbers on file and realize mine has changed from `mobile` to `voip` like mentioned in the article. I think the only ones still tied to my number are a credit card and a neobank, but I could theoretically live without those.
