+# Session management
+
+Once you've authenticated your user with the Sequence APIs and established a session, there are a number of methods available to you to manage the session.
+
+## List Sessions
+
+Use the `ListSessions` method to find all active sessions associated with this user/wallet.
+
+## Drop Session
+
+If you wish to drop/end a session, you can use the `DropSession` method and provide the session id you wish to drop.
+
+## Drop This Session
+
+The `DropThisSession` method can be use if you wish to drop/end the current session. In other words, if you wish to log the user out.
+
+:::note
+If you are using the default `LoginPanel` and you have not enabled `StoreSessionPrivateKeyInSecureStorage` or are on an unsupported platform (see [Recovering Sessions](/sdk/unity/recovering-sessions)), the `WaaSSessionManager` prefab attached to the `LoginPanel` will automatically call this method `OnApplicationQuit`
+:::
+
+## Get Account List 
+
+If you wish to fetch the `Account`s associated with the user's wallet, you can use the `GetAccountList` method.
+
+## Get Id Token
+
+If you wish to retrieve an id token JWT from the Sequence APIs to validate the authentication on your backend, you can use the `GetIdToken` method and optionally provide a nonce.
