For usernames, these three things are helpful to know:
- usernames must be at least 8 characters long
- usernames can contain letters or numbers
- usernames should not contain special characters like $, !, %, etc. (but @ and . are allowed—to accommodate an email address)
If you enter a name and get a user already exists message, it means someone in our database has already reserved that name. You'll need to try another username. For example, if johndoe doesn’t work, try johndoe12 instead.
When you delete a user manually, the username remains unavailable for 30 days. After 30 days, you (or someone else) can reuse that username. Usernames are automatically deleted from Control Center after 12 months of inactivity. These usernames are available immediately after they are deleted.
