This Link Will Self Destruct is a free service for sharing links that are accessible for a finite period of time. This Link Will Self Destruct shortens your URL to make it easier for others to copy or remember. TLWSD allows you to specify how long your shortened URL will be active. You can set a limit of just a few minutes, hours, or days. Password protecting your TWLSD links is an option too.
