# Binding Phone Number and Email

Binding your phone number and email is the first line of defense for your account security, ensuring you receive timely notifications and verification requests during abnormal logins or fund changes.

**Security Recommendations:**

* Use frequently used and secure phone numbers and email addresses; avoid using outdated or inactive emails.
* Enable SMS and email login verification to add an extra layer of security.
* Regularly check for suspicious login alerts or verification emails.

**Friendly Reminder:** Please do not disclose your verification codes sent to your bound email or phone number. **ChainBitX** official staff will never proactively ask you for these codes.
