Multiple thresholds can be added. They will all be tested separately.

Default value

MediaWiki version:

≥ 1.27

/**
 * Limit password attempts to X attempts per Y seconds per IP per account.
 *
 * Value is an array of arrays. Each sub-array must have a key for count
 * (ie count of how many attempts before throttle) and a key for seconds.
 * If the key 'allIPs' (case sensitive) is present, then the limit is
 * just per account instead of per IP per account.
 *
 * @since 1.27 allIps support and multiple limits added in 1.27. Prior
 *   to 1.27 this only supported having a single throttle.
 * @warning Requires $wgMainCacheType to be enabled
