How to unbind a phone number on MEXC? (Account Modification)

Accessing the Account Center

1. Navigate to the official MEXC website at www.mexc.com using a secure browser connection.

2. Enter your registered credentials — username or email and password — to log in successfully.

3. Once authenticated, locate and click the user avatar icon positioned in the top-right corner of the interface.

4. From the dropdown menu that appears, select Account Center to proceed.

Navigating to Security Settings

1. Inside the Account Center, scan the left-hand navigation panel or main content area for the Security Settings section.

2. Click on Security Settings to load the dedicated security management interface.

3. This page organizes all authentication-related controls including login verification methods, fund password configuration, and binding status for contact channels.

4. Look for subsections labeled Phone Number or Bound Phone under the security dashboard.

Initiating the Unbinding Process

1. Within the phone number management area, locate and click the Unbind button adjacent to the currently verified mobile number.

2. A confirmation modal will appear requiring re-authentication — enter your active fund password to verify identity.

3. After successful password validation, the system triggers an SMS verification step; a six-digit code is sent to the number being unbound.

4. Input the received code into the designated field and submit it to authorize termination of the association.

Verification and Finalization

1. Upon correct submission of the SMS code, the platform displays a success message confirming removal of the phone number from the account.

2. The phone number field updates to reflect “Not Bound” or shows an empty state with an option to bind a new number.

3. No further action is required unless immediate re-binding is intended — users may choose to skip this step entirely.

4. The unbinding operation takes effect instantly; no pending status or delay applies once the final confirmation is processed.

Frequently Asked Questions

Q: Can I unbind my phone number without receiving an SMS?A: No. MEXC enforces mandatory SMS verification during unbinding to prevent unauthorized access and preserve account integrity.

Q: What happens if I enter the wrong fund password three times consecutively?A: The system temporarily locks the unbinding function for 15 minutes as a security measure against brute-force attempts.

Q: Is it possible to unbind a phone number used for two-factor authentication while keeping Google Authenticator active?A: Yes. Disabling the phone number does not affect TOTP-based 2FA. Only SMS-based verification is removed.

Q: Will unbinding invalidate existing API keys linked to my account?A: No. API key permissions remain fully operational regardless of phone number binding status changes.
