From mediawiki.org

Custom cookie prefix.
Introduced in version:1.13.0 (r37893)
Removed in version:still in use
Allowed values:(string) or false
Default value:false

Details[edit]

Prefix for cookies and similar browser data (including localStorage). Set it to use a custom one. Setting it to false sets the default of using the database name. Code should ensure browser saved data is prefixed with this value (this is currently done automatically only when WebResponse->setcookie is used without a custom prefix).

The default value is determined in Setup.php :

if ( $wgCookiePrefix === false ) {
        if ( $wgSharedDB && $wgSharedPrefix && in_array( 'user', $wgSharedTables ) ) {
                $wgCookiePrefix = $wgSharedDB . '_' . $wgSharedPrefix;
        } elseif ( $wgSharedDB && in_array( 'user', $wgSharedTables ) ) {
                $wgCookiePrefix = $wgSharedDB;
        } elseif ( $wgDBprefix ) {
                $wgCookiePrefix = $wgDBname . '_' . $wgDBprefix;
        } else {
                $wgCookiePrefix = $wgDBname;
        }
}
