Google (and other companies) are purposely opaque about how they determine whether you have provided enough information to verify you are the owner of the account... Getting it wrong has significant impact on how much the brand is trusted (and for some companies, that's all they have)... Lose it and it's time to shutter! To be fair to Google, they do regularly prompt users to review the security of their account (e.g. with checklists like this: https://support.google.com/accounts/answer/46526?hl=en https://support.google.com/accounts/answer/46526?hl=en).
