logout option

The sidebar widget shows a logout link when in the logged in state, as does the login page. There are several shortcodes you can use (see: https://rocketgeek.com/plugins/wp-members/docs/shortcodes/other-shortcodes/). You can also add a menu item that toggles between a login/logout link (see: https://rocketgeek.com/plugins/wp-members/docs/menus/login-logout-menu-link/)
