單點登陸（英語：Single sign-on，縮寫爲 SSO），又譯爲單一簽入，一種對於許多相互關連，可是又是各自獨立的軟件系統，提供訪問控制的屬性。當擁有這項屬性時，當用戶登陸時，就能夠獲取全部系統的訪問權限，不用對每一個單一系統都逐一登陸。這項功能一般是以輕型目錄訪問協議（LDAP）來實現，在服務器上會將用戶信息存儲到LDAP數據庫中。相同的，單一註銷（single sign-off）就是指，只須要單一的註銷動做，就能夠結束對於多個系統的訪問權限。css

訪問client1
client1將請求導向sso-server
贊成受權
攜帶受權碼code返回client1
client1拿着受權碼請求令牌
返回JWT令牌
client1解析令牌並登陸
client1訪問client2
client2將請求導向sso-server
贊成受權
攜帶受權碼code返回client2
client2拿着受權碼請求令牌
返回JWT令牌
client2解析令牌並登陸

用戶的登陸狀態是由sso-server認證中心來保存的，登陸界面和帳號密碼的驗證也是sso-server認證中心來作的（client1和clien2返回token是不一樣的，但解析出來的用戶信息是同一個用戶）。html
