Persistent Login Nulled is a simple plugin that keeps users logged into your website unless they explicitly choose to log-out.
You can also limit the number of active login sessions your users are allowed to have at one time.
It requires no set-up, just install and save your users time by keeping them logged into your website securely, avoiding the annoyance of forgetting usernames & passwords.
For added security, users can visit their Profile page in the WP Admin area to see how many sessions they have, what device was used and when they were last active. The user can choose to end any session with the click of a button.
