When you experience problems not receiving your OTP (One-Time Password) due to network connection issues with your card provider, you can activate Authenticator as an alternative. Authenticator is an application that generates a verification code that can be used to log into your account without the need for a phone signal. By using Authenticator, you can ensure that you can still access your account and make withdrawal transactions in your Indodax account safely and smoothly. Activating Authenticator also adds an additional layer of security to protect your account from unauthorized access. For steps to activate Authenticator, please follow this link.
