What is a username?

Usernames are how people find you to send you a contact request. Nobody else can see your usernames, not even your Air contacts.

• You can have up to five.
• Each username can only belong to one person.
• When you remove a username, people can’t use it to find you, and someone else can take it.
• Usernames are 5 to 63 characters long and can contain lowercase letters, numbers, and dashes (-). They can’t start with a number or a dash, or have two dashes in a row.
