WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
BTW, there is one more way - if your devices are connecting to some kind of central hub, e.g. MQTT broker, they may send a "sticky" (retained) message with discovery info to some known topic - Tasmota is using this way, devices are publishing to tasmota/discovery/id and every time MQTT client connects it gets lastly updated autoconf info.
