How to link a phone number to Bybit? (Security link)

Accessing the Security Settings

1. Log in to your Bybit account using your registered email and password.

2. Navigate to the top-right corner of the dashboard and click on your profile icon.
3. Select Security Center from the dropdown menu.
4. Ensure you are on the Account Security tab within the Security Center interface.
5. Locate the Phone Number section, which displays current status and binding options.

Initiating Phone Number Binding

1. Click the Bind button next to the Phone Number field.

2. Enter your full phone number including country code in the designated input field.
3. Bybit will send a six-digit SMS verification code to the provided number.
4. Input the received code into the verification field within two minutes before expiration.
5. Confirm submission by clicking Verify; successful binding triggers an on-screen success message.

Handling Verification Failures

1. If the SMS does not arrive within 60 seconds, click Resend Code to trigger a new delivery.

2. Verify that the entered number matches your active mobile device and supports SMS reception.
3. Check for carrier-level blocks or spam filters that may intercept the message.
4. Avoid using virtual numbers, VoIP services, or temporary SMS platforms as they are unsupported.
5. Reattempt binding only after confirming network connectivity and correct number formatting.

Two-Factor Authentication Integration

1. Once bound, the phone number becomes eligible for use in SMS-based two-factor authentication (2FA).

2. Go to the Two-Factor Authentication section in Security Center to enable SMS 2FA.
3. Disable Google Authenticator or email 2FA before activating SMS 2FA if multiple methods conflict.
4. Each login attempt will require entering the one-time code sent via SMS to the verified number.
5. Loss of access to the linked phone triggers mandatory identity verification through Bybit’s support escalation path.

Frequently Asked Questions

Q: Can I bind more than one phone number to a single Bybit account?A: No. Bybit permits only one active phone number per account for security consistency and fraud prevention.

Q: What happens if I change my SIM card but keep the same number?A: The binding remains valid as long as the number itself is unchanged and functional for SMS receipt.

Q: Is it possible to remove a phone number without replacing it with another?A: Removal requires completing identity verification via live video call or document upload; unbinding leaves the account without SMS recovery capability.

Q: Why does Bybit reject my number during binding even though it's correct?A: Rejection occurs if the number is already registered to another Bybit account, flagged for suspicious activity, or belongs to a restricted jurisdiction.
