Digital identity refers to a person's collective online presence across websites, while digital footprint is the traceable record of a user's internet interactions. Your digital footprint consists of the websites you visit and all online content you create or consume, including social media posts, reviews, and search histories. Both your digital identity and footprint can be used to build a profile about you and your online behaviors. It is important to manage your digital identity and footprint carefully to avoid potential issues like job loss that may occur from information publicly available online.
