Unfortunately, our system does not permit the change of Usernames. PIA account usernames are always a "p" followed by seven digits, and they remain the same for the duration of the account.
For security reasons, we have purposely made it difficult for individuals to remember or guess your username information. As our service centers around the highest degree of security and privacy, this is just one of the various precautions we take to keep you, your information and connection safe.
We apologize for any inconvenience this may cause!
