**Canonical:** https://apis.io/apis/sk-telecom/sk-telecom-t-id-api/  
**Provider:** SK Telecom — https://apis.io/providers/sk-telecom/  
**Documentation:** https://developers.t-id.co.kr/

SK Telecom T ID Login API is one of 15 APIs that [SK Telecom](https://apis.io/providers/sk-telecom/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity, Authentication, and Single Sign-On. The published artifact set on APIs.io includes API documentation.

T ID is SK Telecom's federated identity service, the single sign-on used across SK Telecom and SK affiliate services with roughly 15 million registered users. Third parties integrate T ID login through the T ID Developers channel portal. No .well-known/openid-configuration or .well-known/oauth-authorization-server document is served — those paths return the SPA shell.
