Extending auto log out with Plugins, and how long is safe?

I am just wondering if there are any other plugins available for this: https://premium.wpmudev.org/blog/how-to-extend-the-auto-logout-period-in-wordpress/

Looks like the Plugin wasn't updated in a few years and I prefer not adding that code to functions.php.

And while I am here I was wondering, how long extending the sessions is considered safe from the 2 days (2 weeks with checkbox) standard?

Ideally I would like my users to never log out but I guess there are some potential security risks and privacy concerns?

Thanks :slight_smile:
