A ‘Legacy Contact’ is a specific term that refers to an individual that has been appointed to be in charge of taking care of one's internet accounts after they pass away. This person can be your executor for your estate or you can select another individual to manage your digital assets. Not all social media accounts and companies allow you to assign a legacy contact. In this case, you should specifically assign a Legacy Contact in your will.
This assigned title allows an individual to control a social media account or close a memorialised account. An account can be memorialised by a close family or friend by presenting proof of death, like death certificate or obituary. A Legacy Contact has the ability to manage tribute posts on your profile, which includes deciding who can post and who can see posts, deleting posts, and removing tags.
