Securing your digital assets starts with strengthening your account’s authentication. One of the most effective ways to protect your online financial platforms is by linking an authenticator app. This guide walks you through the step-by-step process of connecting an authenticator app—such as Google Authenticator or Microsoft Authenticator—to your account, whether you're using the OKX mobile app or accessing your account via a web browser.
By enabling two-factor authentication (2FA) via an authenticator app, you significantly reduce the risk of unauthorized access. Unlike SMS-based verification, which can be vulnerable to SIM-swapping attacks, authenticator apps generate time-based one-time passwords (TOTP) locally on your device, offering a higher level of security.

Why Use an Authenticator App?
An authenticator app adds a critical layer of protection to your account. Even if someone obtains your password, they won’t be able to log in without the temporary 6-digit code generated by your authenticator app.

Frequently Asked Questions (FAQ)
Q: What is an authenticator app?
An authenticator app generates time-sensitive, one-time passwords used for two-factor authentication (2FA). It enhances account security by requiring a second verification step beyond just a password.
Q: Can I use any authenticator app?
Yes. While Google Authenticator and Microsoft Authenticator are popular choices, any TOTP-compatible app (like Authy or Duo) will work with OKX.
Q: What should I do if I lose access to my authenticator app?
If you lose your device or uninstall the app, you can recover access using backup codes or by going through identity verification. It's crucial to save recovery options securely during setup.
Q: Why are withdrawals disabled for 24 hours after changing my authenticator?
This is a security delay designed to prevent unauthorized users from immediately transferring funds after gaining access. It gives you time to detect and respond to suspicious activity.
Q: Is using an authenticator app better than SMS verification?
Yes. Authenticator apps are more secure than SMS because they aren’t vulnerable to SIM-swapping attacks and generate codes offline without relying on cellular networks.
Q: Do I need internet access for my authenticator app to work?
No. Authenticator apps generate codes based on a shared secret and synchronized time, so they work even without internet or cellular service.
