Security is one of KuCoin's top concerns. To protect your account and avoid any potential theft of your assets, KuCoin has introduced a mobile phone binding feature.

To ensure your account security, it is recommended that you implement multiple security settings at the same time. For instance, a good security combination can be Google 2FA Verification + Email Binding + Trading Password or Mobile Phone Binding + Trading Password.

This article shows you the steps for mobile phone binding and changing.
