# What authentication methods does the Unlimited Plan support?

The Unlimited Plan only supports **Username & Password authentication**.

A dedicated sub-account will be automatically assigned to your Unlimited Plan. If this is your first purchase, the system will generate it when you activate your order. You can change the password of this sub-account, but the username cannot be modified.
