+include an extra response parameter, ``soft_logout``, to indicate if the client's
+persisted information can be retained. This defaults to ``false``, indicating
+that the server has destroyed the session. Any persisted state held by the client,
+such as encryption keys and device information, will not be able to be reused.
When ``soft_logout`` is true, the client can acquire a new access token by
specifying the device ID it is already using to the login API. In most cases
a ``soft_logout: true`` response indicates that the user's session has expired
on the server-side and the user simply needs to provide their credentials again.
-If ``soft_logout`` is ``false``, the client will not be able to reuse the device
-information it already has - the server has destroyed the session.
+In either case, the client's previously known access token will no longer function.
