How can I keep a user logged in after they close the browser? I don't want the user to have to log into the site every time they visit it. I have increased session lifetime, but that does not work when the browser is closed. Is there a way to accomplish this?
You need to have them click on the Remember Me check box when they login to the site and this will store a RememberMe cookie in the users' browser storage that will be read next time they visit the site and automatically log them in.
If you don't see the 'Remember Me' check box on your front end login you need to look at the Plugins and make sure the 'System - Remember Me' plugin is enabled.
Remember Me works for around 30 days and then the user will have to login again before they are remembered for another 30 days.
