About
At this time, it is not possible to change the username of a Kraken account.
If you would like to change the username because you feel it is not secure enough (perhaps it is too easy to guess or you accidentally made it public), we recommend that you open a new account with a different username.
If you create a new account, you can verify that account using the same information and documents you had provided for your original account, if they are still valid.
Note: If you create a new account with a different username, you will not be able to transfer your current account's assets directly into the new one.
