Online identities refer to the personas that individuals create and maintain on the internet. These identities can include usernames, profiles, and the content shared on social media platforms like Facebook, Instagram, or Twitter. They often reflect personal interests, beliefs, and social connections, allowing users to interact with others in digital spaces. The concept of online identities also encompasses the idea of privacy and security. Users must navigate how much personal information to share and how it may affect their real-life reputation. Managing online identities is crucial, as they can influence perceptions in both personal and professional contexts.
