Each time you login to your blog WordPress creates a session cookie which is used to authenticate you. 
By default if someone somehow gets your cookies he (or she) is able to use them to compromise your blog 
(even without having to know your password!). To prevent this you may want to make your auth cookies 
ip-dependent so that they could be valid only for that ip which you used during login.
Use this plugin only if you have a static IP or dynamic which doesn’t change too often. Otherwise, you’ll 
have to enter your login and password each time your IP changes.

IP Dependent Cookies

Plugin IP Dependent Cookies makes your Wordpress installation more secure adding your IP to salt (which makes cookies IP-dependent).

The Escape Button is a simple floating action button that allows users to quickly and safely exit your website in case of emergency. We originally developed this tool to support survivors of sexual and domestic violence and hope it can be useful for the community as well.
The Escape Button is built to handle both situations where the user or browser does not have Javascript enabled and when it does.
It is possible to override the styling of the Escape Button in your own stylesheet.

We developed the Our Wave Escape Button (available in the bottom right of our website) to help protect our users in unsafe situations.
