Protecting exchange two-factor authentication from SIM swaps in Nigeria
If your exchange login depends on SMS, whoever controls your number can try to reset your account. How users in Nigeria can move Binance, OKX, Bybit or Bitget accounts to stronger methods and harden their SIM.

In Nigeria, the phone number does a lot of work: bank alerts, mobile money, OTPs and exchange codes often all arrive by SMS on the same line. That makes the SIM a valuable target. In a SIM swap, a fraudster convinces someone at a provider to move your number to a new card, and suddenly your codes go to them. Exchange accounts on Binance, OKX, Bybit or Bitget that rely on SMS alone are exposed. This guide explains how to move to an authenticator app or passkey, how to harden the SIM itself, and what warning signs suggest a swap may be under way.
Switch to a stronger factor
In the security settings of each exchange, add an authenticator app or a passkey, following the official help pages. Save the authenticator backup key on paper and store it away from the phone. Test the new method by logging out and back in, and only then remove SMS as a second factor where the platform allows it.
Harden the SIM
Ask your network provider whether you can set a SIM PIN or extra verification for SIM replacement, and keep your NIN and registration details accurate. Avoid sharing your phone number widely in public groups, and be careful with calls asking you to confirm personal details for an upgrade. These are often the first step of a swap attempt.
Know the warning signs
A sudden loss of signal when your area normally has coverage, messages from your provider about a SIM change you did not request, or login alerts from your exchange at odd hours should all be treated as urgent. Contact your provider through official channels immediately and check your exchange accounts from another trusted device.
Lock things down quickly
If you suspect a swap, change your exchange passwords from a trusted device, review two-factor settings, end all sessions and remove unknown withdrawal addresses. Use the account freeze option if available. Then contact exchange support through the official app or website, and report the incident to your provider so the number can be recovered. Afterwards, write down what happened and when, because a clear timeline makes both the provider and the exchange respond faster.
