Well, this is a tricky situation. At what point did Google agree to become the world's free email provider? We have to decide where their social obligation outranks their share holder obligation. And by "we," I include everyone from users, technology providers, and especially governments that require email addresses to get basic services, everyone. A modest proposal. Can one YubiKey serve several email accounts? Ask patrons to sign up for a library card. Register each library card with one key, such that one key can serve many patrons. Help them enroll with multi-factor authentication. Whenever they need it, simply request the token from the librarian desk. (Put the token on a giant brick or yardstick, so that it never leaves the library. Sort of like how they do at gas station bathrooms.)
