Every time you try to log in to the site, the RichExchanger exchanger sсript automatically records the authorization log.
The authorization log is recorded both in the case of successful and unsuccessful authorization on the site.
The logs are located in the "Users" - "Authorization log" section.
The logs are stored for a certain number of days, after which they are permanently deleted.
The logs are deleted by a cron task. You can configure the task in the "Settings" - "Cron" - "dеlete user authorization information in the system" section. By default, deletion occurs "on the site", every 24 hours. That is, every 24 hours, the system deletes logs that are older than 30 days (unless otherwise specified in the logging settings).
