Authentication for React

Among 10 makers' products we track that are built with React, here's what they chose for authentication — each counted from a live-product source.

Hosted service or library in your own app. Hosted services give you UI, MFA and security updates for a monthly bill and some lock-in; libraries keep users in your own database for free, and you own the upkeep.
