MediaWiki version:

The purpose of this cookie is to allow having a different (usually longer, but this is not enforced) duration for "Keep me logged in (for up to $1 days)" login-related cookies. This means you can e.g. set the standard cookie duration (widely used for MW cookies) to 30 days, but set the "Keep me logged in (for up to $1 days)" duration to a year.

Logins where the "keep me logged in" option is not checked are entirely unaffected by this setting.

Logins where "keep me logged in" is set use a mechanism that can recover from server-side session expiry, so the lifetime of the extended login is unaffected by $wgObjectCacheSessionExpiry.

The values mean:

  • null - MW will follow $wgCookieExpiration instead.
  • Positive integer - Duration of "Keep me logged in (for up to $1 days)" sessions, in seconds.
  • 0 - "Keep me logged in (for up to $1 days)" sessions will last until the browser closes.
