How to Log into OKX After Switching Phones: Device Migration Guide
After switching phones, logging intoOKXrequires no special steps—simply follow the normal login process for a new device. Your account, password, and assets are stored on the server, so changing devices does not affect them. The core issue is:the new device is treated as an "unauthorized device" by the system, requiring identity verification to authorize it.

Preparation: Ensure You Can Complete Verification
Logging in on a new device requires at least one verification method to be available. It is recommended to confirm the following three items in advance:
Your phone number can receive SMS or voice calls: For receiving verification codes or voice calls.
Your linked email can receive messages: For receiving verification emails.
Google Authenticator (GA) is recoverable on the new phone: If you previously bound GA, youmust retain the original secret keyto restore GA on the new device. GA recovery relies on the key you saved (QR code or 16-character string), not your phone number or email.
If at least one of these three is functional, you can complete the login on the new device.
Three Verification Methods: Choose What Works for You
When logging in on a new device, the system will offer one or more of the following verification methods, depending on what is displayed on the screen:
1. Device Verification (Fastest, but Requires Old Phone)A verification notification will appear on the OKX app on your old phone. Tap "Yes, it's me, allow login," then follow the prompts to enter the security code from the new device into the old one to complete authorization.
2. Phone Number Verification (Not Possible if Old Number is Deactivated)
SMS Code: Enter the verification code sent to your linked phone number.
Voice Call: The system will call your phone number. After answering, press "1" as instructed to authorize the login.
Note: Voice verification is limited to 5 attempts per hour; exceeding this requires waiting until the next hour.
3. Email VerificationThe system will send a verification email to your linked email address. Click the link in the email to complete authorization. If the link cannot be clicked directly, copy and paste it into a browser.
Handling Different Scenarios
| Scenario | Action |
|---|---|
| Old phone available, just switching to a new one | Use "Device Verification" first—it is the fastest and requires no additional code entry. |
| Old phone lost, but phone number still works | Select "Phone Verification" during login, and receive an SMS or voice call to authorize. |
| Old phone and phone number both unusable, but email is linked | Choose "Email Verification" and click the verification link in your email. |
| None of the above methods are available | Send a photo of your ID via the linked email to official customer service at |
What to Do Before Switching Phones (If You Haven't Yet)
Back up your GA secret key: This is the most commonly overlooked step. If you forget to back it up and have no other verification methods, you will be unable to log in independently. When binding GA, the system always prompts you to save the key—be sure to screenshot or write it down and store it offline.
Ensure verification methods are complete: Bind your phone number, email, and Google Authenticator simultaneously so that if one method fails, you have a backup.
Facial Recognition Verification
When logging into OKX on a new device, if your account has completed real-name verification, you may be required to undergo facial recognition to confirm you are the account owner. This must be done by the person who completed the real-name verification. If facial recognition fails, ensure the app is updated to the latest version, camera permissions are granted, and you are in a well-lit environment with no obstructions on your face.
Post-Login Checklist
After successful login, it is recommended to do the following:
Go to [Security Center] > "Device Management," check the list of currently logged-in devices, and remove any unfamiliar devices.
Confirm that your security settings (password, 2FA, anti-phishing code) have not been altered.

FAQ
Q: What if the OKX verification code in Google Authenticator is gone after switching phones?A: If you havesaved the secret key generated when binding GA (QR code or 16-character string), install Google Authenticator on your new phone, tap "+" and select "Enter provided key," then paste the string to restore it.This key does not automatically transfer with your phone data—only you can back it up. If the key is lost, you will need to contact customer service for manual unbinding, which is a lengthy process.
Q: Can I still log into OKX if my old phone number is no longer in use?A: Yes, provided you havelinked an email or Google Authenticator. During login, select "Switch verification method" and use email or GA to complete verification. If you only linked a phone number and it is no longer active, you will need to contact human customer service for assistance.
