Users provide a username and password, which are compared with stored database credentials. If matched, access is granted.<br \/>\nWhile relational databases like <a class=\"ack-link-color\" href=\"https:\/\/accuweb.cloud\/database\/mysql-hosting\" target=\"_blank\" rel=\"noopener\">MySQL<\/a> or <a class=\"ack-link-color\" href=\"https:\/\/accuweb.cloud\/database\/postgresql-hosting\" target=\"_blank\" rel=\"noopener\">PostgreSQL<\/a> commonly store login credentials, this approach has challenges:<\/p>\n<p><b>&#8211; Database Overload:<\/b>\u00a0Every login request requires querying the database, impacting performance as other tasks run simultaneously.<br \/>\n<b>&#8211; Scalability Issues:\u00a0<\/b>Handling thousands of login requests can strain traditional databases.\u00a0Using Redis, a fast in-memory data store, can alleviate these issues by caching login data.
