Maybe a Government-supplied email address that is only accessible from libraries?
I would hope that libraries would have fixed IP addresses, so surely that could be factored into the authentication process? Some FIDO keys used to be able to be bought for as little as $5 (https://wiert.me/category/power-user/security/u2f-fido-secur...) so it shouldn't be beyond the budget of any self-respecting town/county/state?
