Why Authfyio

The auth layer teams actually enjoy shipping.

Passkeys, magic links, OAuth
Every modern auth method, one consistent API.
Open-source & self-host
No vendor lock-in. Inspect, audit, fork.
Multi-tenant from day one
Org → App → Instance hierarchy built in.

"We migrated from our previous provider in a weekend. Authfyio's multi-tenant model just mapped onto our product."
