It was only after I wrote it that it dawned on me that I use my Google Account for authentication with a number of third parties. About 90% of things I use email + password (and 2FA where available), but that last 10% is a mix of Google authenticated, or Twitter authenticated. Because Google Accounts are an identity provider, even if I wanted to move I really have no way to do that now.
