Ask HN: How to recover Google auth after phone stolen?

A Hacker News user describes being locked out of all their Google-connected accounts after their phone was stolen, as the standard recovery options (old phone, current phone, or old email) are all inaccessible. Commenters suggest that recovery backup codes and SIM card replacement might help, but note that Google generally lacks human support for such situations and recommend saving recovery keys beforehand or considering alternatives to Google services.
