Never share your username with anyone.
When discussing your account (even if it's with Kraken Support), only use the Public Account ID. If someone asks for your username, it's most likely a phishing scam.
Your Public Account ID can be found under the Settings > Account page of your account. Hover over your name in the upper right corner to navigate to Settings > Account. It starts with "AA", uses numbers and UPPER-CASE letters, and is 16 characters long in total.
Finding your Public Account ID on the Kraken app
To find your Public Account ID on the Kraken app, simply go to the App Setting tab, click on "Account details" and your account number will appear. You can click it to copy the ID to your clipboard as well.
Public Account ID vs Username
The purpose of the public account ID is so that you can keep your sign-in username private.
|Public Account ID||Username|
|Created by Kraken (automatically) after signup||Created by you during signup|
|Used for discussing your account with 3rd parties
(including Kraken Support)
|Used only for sign-in|
|Cannot be changed||Cannot be changed|
