|

|

``ds_actor`` cookies can optionally include a signed expiry timestamp, after which the cookies will no longer be valid. Authentication plugins may chose to use this mechanism to limit the lifetime of the cookie. For example, if a plugin implements single-sign-on against another source it may decide to set short-lived cookies so that if the user is removed from the SSO system their existing Datasette cookies will stop working shortly afterwards.
|
||||
|
||||
To include an expiry, add a ``"e"`` key to the cookie value containing a `base62-encoded integer <https://pypi.org/project/python-baseconv/>`__ representing the timestamp when the cookie should expire. For example, here's how to set a cookie that expires after 24 hours:
