This plugin allows you to create logout button anywhere in Joomla! website. Currently if you create menu link for logout, user is redirected to a page and after that if user clicks on Logout button, he/she will be logged out. And there is another way is by using Login module, but it takes some extra place to show module. By using this plugin you just need to show a link/button or any other html DOM, which supports click event. Give this element class "f90-logout-button" and you are done with it. Lets follow the steps listed below.
<a href="#" class="f90-logout-button">Logout</a>
