How to Enable Anti-Phishing Codes on MEXC to Verify Official Exchange Emails?

Understanding Anti-Phishing Codes in Crypto Exchanges

1. Anti-phishing codes are unique alphanumeric strings generated by centralized cryptocurrency exchanges to authenticate official email communications.

2. These codes are bound to a user’s registered email and cannot be altered without multi-factor verification.

3. When enabled, every system-generated email from MEXC—such as withdrawal confirmations, login alerts, or security notifications—includes the user-specific anti-phishing code in its footer.

4. The presence of a valid, matching code confirms that the message originated from MEXC’s authorized mail infrastructure and was not spoofed by attackers.

5. Unlike generic email signatures, anti-phishing codes are dynamically rotated per user and never reused across accounts or sessions.

Step-by-Step Activation Process on MEXC

1. Log into your MEXC account using verified credentials and complete 2FA authentication before accessing security settings.

2. Navigate to Account Security → Email Protection → Anti-Phishing Code.

3. Click Enable and enter your current password plus a valid TOTP code from your authenticator app.

4. Confirm the action via SMS or email verification sent to your registered mobile number or primary inbox.

5. Upon successful activation, MEXC displays a 10-character code in green font: MXC7K9R2FQ.

Verification Mechanics for Incoming Emails

1. Every official MEXC email contains a fixed header line: “This is an automated message from MEXC Global.”

2. Immediately below the header, a dedicated line reads: “Anti-Phishing Code: [your_code].”

3. Users must manually compare this code with the one displayed in their MEXC security dashboard under Email Protection.

4. If the code is missing, mismatched, truncated, or contains non-alphanumeric characters, the email must be treated as unverified.

5. MEXC does not embed anti-phishing codes in HTML email bodies or image-based footers; they appear only as plain-text strings in UTF-8 encoded messages.

Security Limitations and Known Constraints

1. Anti-phishing codes do not protect against compromised sender domains outside MEXC’s infrastructure, such as phishing emails mimicking MEXC support via third-party domains.

2. The code remains static until manually regenerated; users must initiate regeneration after any suspected credential exposure.

3. No API or mobile app interface exposes the anti-phishing code—only the web-based security center displays it.

4. Emails sent through MEXC’s internal notification system (e.g., in-app banners) do not carry anti-phishing codes, as they bypass SMTP entirely.

5. Forwarded MEXC emails lose code validity because forwarding breaks the cryptographic binding between the original message hash and the registered email address.

Frequently Asked Questions

Q: Can I use the same anti-phishing code across multiple email addresses linked to my MEXC account? A: No. Each registered email address requires its own independently generated anti-phishing code. MEXC assigns one code per verified email, and enabling a second email triggers generation of a separate code.

Q: Does the anti-phishing code change automatically after 30 days? A: No. The code remains unchanged until manually regenerated by the user. MEXC does not enforce time-based rotation or expiration policies for these codes.

Q: What happens if I delete my registered email and add a new one? A: The old anti-phishing code becomes permanently invalid. A new code is generated only after the replacement email completes full verification, including click-through confirmation and CAPTCHA challenges.

Q: Why doesn’t the anti-phishing code appear in emails sent from MEXC’s mobile app push notification system? A: Push notifications operate outside SMTP channels and lack email headers or footers. Anti-phishing codes are strictly tied to SMTP-delivered messages and do not extend to in-app or OS-level alerts.
