How to enable SMS authentication on MEXC

If you’re using a crypto exchange, keeping your account secure should be a top priority. One of the simplest ways to add protection is enabling SMS authentication (often referred to as SMS-based 2FA). It adds an extra verification step whenever you log in or perform sensitive actions, helping reduce the risk of unauthorized access.

This guide walks you through turning on SMS authentication on MEXC, what to expect, and when it might be the best option for you.

Why enable SMS authentication on MEXC?

SMS authentication works by sending a one-time code to the phone number linked to your account. Even if someone obtains your password, they’d still need that code to access your account or complete certain actions.

Compared to accounts with only a password, SMS authentication provides a meaningful improvement in security and is typically easy to set up.

That said, no security method is perfect. SMS can be weaker than app-based authenticator methods in some scenarios, but it’s still better than having no second factor at all.

What you’ll need before you start

Before you try to enable SMS authentication, make sure you have:

• Access to your phone number (you can receive text messages)
• Your MEXC login details
• Time to complete the verification steps (you’ll typically receive a code by SMS)

If you plan to use SMS for important actions (like withdrawal approvals), double-check that your phone number is correct in your account settings.

Step-by-step guide: enabling SMS authentication on MEXC

The exact menu wording can vary slightly depending on the app version or website layout, but the process is generally the same.

1) Log in to your MEXC account

• Go to the MEXC website or open the MEXC app.
• Sign in using your username/email and password.

2) Open account security settings

Look for an area named something like:

• Security Center
• Account Security
• 2FA / Verification

On the site, this is usually found under Profile or Security settings.

3) Choose SMS authentication (SMS 2FA)

In the security settings, find the option related to two-factor authentication and select SMS.

You may see multiple methods such as:

• Email verification
• Authenticator app (like Google Authenticator)
• SMS verification

Select SMS verification.

4) Confirm your phone number

MEXC will either:

• Ask you to enter your phone number, or
• Show the phone number already linked to your account

Make sure the number is correct. If it’s not, update it following MEXC’s instructions.

5) Request the SMS code

After you enter/select your phone number, click Send Code (or a similar button).

You should receive a text message with a short verification code.

6) Enter the code and enable SMS authentication

• Enter the code into the provided field
• Submit/confirm to activate SMS authentication

If the code is correct and within the valid time window, SMS authentication should be enabled.

7) Test or review your security settings

After enabling it, review whether:

• SMS is required for login
• SMS is required for withdrawals or other sensitive actions

Some platforms allow you to choose which actions trigger SMS verification. Make sure the settings match your preference for security.

Troubleshooting common issues

“I didn’t receive the SMS code”

This can happen due to network delays or number issues. Try:

• Confirming your phone number is correct
• Checking for message service delays (wait a few minutes)
• Ensuring your phone can receive texts
• Trying again and requesting a new code

If it still doesn’t work, you may need to contact MEXC support or use another authentication method (like an authenticator app).

“The code is invalid”

SMS codes usually expire quickly. Make sure you:

• Enter the code immediately
• Don’t include extra spaces or incorrect digits
• Request a new code if the old one may have expired

You changed your phone number

If you no longer have access to the old number, you’ll generally need to update your phone number through account settings before enabling SMS authentication again. If updates are restricted for security reasons, you may be asked to complete additional verification.

Guide: choosing SMS verification for login vs withdrawals

Some users enable SMS authentication but forget to turn on verification for withdrawals or other critical actions (if the platform offers those toggles). If you want stronger protection, consider enabling SMS verification for:

• Withdrawal requests
• Changing security settings
• High-risk actions (where available)

Even if SMS is enabled for login, requiring SMS for withdrawals adds extra safety—especially if your password is ever compromised.

Pros and cons of SMS authentication on MEXC

Like any security tool, SMS has advantages and trade-offs.

Pros

• Easy to set up: Usually quick and straightforward.
• No extra app needed: You only need a working phone number.
• Adds a second layer: Helps protect against password-only access.
• Works for many users: Useful if you don’t want to install an authenticator app.

Cons

• Dependent on mobile service: Delays or outages can prevent you from receiving codes.
• Potential SIM-related risks: In some cases, SMS can be vulnerable compared to authenticator apps.
• Phone number changes require care: If you lose access to your number, you may face account access challenges.
• Less secure than authenticator apps: App-based codes typically provide stronger protection.

Tips to improve account security beyond SMS

If you want to maximize your safety while still using SMS, consider these best practices:

• Use a strong, unique password (not reused from other sites).
• Avoid phishing links: Always verify you’re on the correct MEXC domain.
• Consider using an authenticator app if you have the option. Authenticator-based 2FA generally offers better security.
• Review your withdrawal settings and whitelist features (if available).
• Keep your phone number current and ensure you can receive texts reliably.

Conclusion

Enabling SMS authentication on MEXC is a practical way to add an extra security step to your account. The setup is typically quick: log in, find Security settings, choose SMS verification, confirm your phone number, and verify with the code sent to your device.

Just remember that while SMS helps protect your account, it’s not always the strongest method available. If you can, pairing SMS with other safeguards—or opting for an authenticator app—may provide even better protection.
