Online identity refers to the persona or profile that an individual creates and maintains on the internet. This identity can include social media accounts, email addresses, and any other digital footprints left behind, such as comments or posts. It reflects how a person presents themselves online and can influence their interactions with others. Managing online identity is important for personal branding and privacy. Individuals should be aware of the information they share and how it may be perceived by others. Tools like privacy settings and digital footprints can help users control their online presence and protect their personal information.
