Protecting Your Account

A few simple habits go a long way in keeping your account safe:

  1. Never share your password, email verification code, full card number, or security code with anyone, including someone who claims to be U9 support.
  2. Only manage your account and card through the official app and official support channels.
  3. If you notice a suspicious transaction, freeze your card right away and contact U9 support.
  4. If you change devices, or think your account information may have been exposed, change your password promptly and review the login activity in your account settings.
