WPAutoLogin

This plugin allows admininstators to generate autologin links for their 
WordPress website, logging in visitors under a certain user name. Administrators 
can edit (generate and delete) autologin links for users, users can only view 
their autologin links. Note that This plugin bypasses the standard 
authentication method of wordpress via login and password and should only be 
used if you understand the security issues mentioned below and on the 
<a href="http://www.craftware.nl/wordpress-autologin/" rel="nofollow ugc">plugin website</a>.
Usage
Once this plugin is activated, administrators can generate autologin links on 
the edit profile administration pages for different users. Users can view their 
autlogin links on their profile pages. Autologin links are of the form:
http://yourwebsite/[subdirectory/]?autologin_code=ABC123
For more convenience it is possible since version 1.05 to generate login links 
directly using the wordpress, site-preview functionality. When viewing the page 
while being logged in as an administrator, the top-bar will show an extra item 
“Auto-login link”. When pointing at the menu item, a dropdown list will list 
all users for whom autologin links were generated on their profile pages. When 
clicking on one of the users, a popup will open showing the link that will 
automatically login a visitor as the selected user and bring him to the 
current page.
Security issues
Since autologin links are meant to be an OPEN way to login to 
your website and can be viewed by users on their profile, it might be considered 
an INSECURE plugin for WordPress. I did my best to make it as secure as possible 
to fit my own needs, but this lead to some design choices which might not sit 
well with all administrators:
Autologin codes are saved as plain text. This means that anyone who can 
execute queries on the WordPress database (plugins, administrators, system 
administrators) can obtain the autologin code for a certain user. I planned an 
extension of this plugin where login codes are hashed. However, this again has 
the disadvantage that noone can redisplay a once generated login link.
This is the most severe problem. For a full self-assesment of possible security 
issues regarding this problem, please visit the

Plugin authors that create free plugins love people complaining and giving a 1-star rating instead of creating a support thread.

Auto Hide Admin Bar makes the WordPress Toolbar disappear – and reappear when hovering the mouse pointer over the top of the browser window. 
You end up with a clean view of your site, and keep having access to the WordPress Toolbar.
