Simple Login SC does just what it means
Simple Login SC does not mess with other plugins because it does just login or logout a user. Nothing more. Nothing less. 
It uses the core functions of WordPress thus not slowing down your site. No fancy stuff or hard settings. This is just a login plugin!
Using Simple Login SC is absolutely easy
Just type the shortcode where you want a login form to show. 
Use [sl_shortcode] shortcode to add a login form to a page, post or in a text/html widget. 
You can optionally set the labels for “username”, “password”, the submit button and/or the welcome message, the logout text. Just by adding text to the shortcode.
Usage
Example: [sl_shortcode username_label=”What is your name?” password_label=”Password Please!” button_text=”Let me in!” welcome_text=”Hello” logouttext=”Let’s go outside!”]
This is very useful if the language pack is not available in your language or if you have a multilangual site running WPML. 
If you do not set one or all of the optional text, the default text of WordPress and the plugin will be used.

Note: This plugin still works but it doesn’t really contain any major features that the native Text widget is missing. The plugin is no longer in active developement.
This plugin adds a rich text widget where the content is edited using the standard WordPress visual editor which most users already are familiar with. 
It uses the WP core function wp_editor() without adding a custom post type post for each widget making the widget quicker and simpler to edit.

WP Editor Widget

I used it to add client instructions to an admin page. This makes adding screenshots and video quite easy.
