Let Your Visitors Sign In — End-User Auth in FlowFn

Your app has users — not FlowFn accounts, but your customers: café members with a loyalty balance, a client portal's clients, a community's members. FlowFn's end-user auth lets those visitors sign up and log in to your published site, with their accounts stored as rows in a Data Sheet, passwords hashed, and pages gated behind a login — no separate auth service to run.
