Single Sign On

Login/Register User using SSO

PhonePe works on a Single Sign-On (SSO) mechanism. SSO provides a seamless login flow. When the Merchant Switch needs to verify the identity of a user, it can use the SSO API to silently SignIn/SignUp the user. When you call the SSO API, PhonePe displays a popup where the user can explicitly specify his consent on sharing his details with the Merchant.
