authentication:authentication-ds-actor-expiry,authentication,authentication-ds-actor-expiry,Including an expiry time,"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 representing the timestamp when the cookie should expire. For example, here's how to set a cookie that expires after 24 hours: 
                 import time
from datasette.utils import baseconv

expires_at = int(time.time()) + (24 * 60 * 60)

response = Response.redirect(""/"")
response.set_cookie(
    ""ds_actor"",
    datasette.sign(
        {
            ""a"": {""id"": ""cleopaws""},
            ""e"": baseconv.base62.encode(expires_at),
        },
        ""actor"",
    ),
) 
                 The resulting cookie will encode data that looks something like this: 
                 {
    ""a"": {
        ""id"": ""cleopaws""
    },
    ""e"": ""1jjSji""
