Your Online and Offline Identity As more time is spent online, your identity, both online and offline, can affect your life. Your offline identity is the person who your friends and family interact with on a daily basis at home, at school, or work. They know your personal information, such as your name, age, or where you live. Your online identity is who you are in cyberspace. Your online identity is how you present yourself to others online. This online identity should only reveal a limited amount of information about you. You should take care when choosing a username or alias for your online identity. The username should not include any personal information. It should be something appropriate and respectful. This username should not lead strangers to think you are an easy target for cybercrimes or unwanted attention.
