Binance 2FA and account security for holders

Layered account defense

Holders treat Binance as a high-value email: if someone owns the login, they own the money. Passwords alone are not enough. Authenticator 2FA, withdrawal controls, and phishing hygiene form the minimum stack for serious balances.

Authenticator 2FA (prefer over SMS)

1. Use a reputable authenticator app on a device you control.
2. Scan the Binance QR during setup; store backup codes offline immediately.
3. Avoid SMS as sole 2FA when authenticator is available — SIM-swap risk is real.
4. If you lose the phone, recovery depends on pre-saved codes and official support — document the process before you need it.

Controls that stop silent drains

• Withdrawal address whitelist — only pre-approved destinations; add delay for new addresses. Withdrawal security guide.
• Anti-phishing code — custom string Binance includes in real emails so fakes are obvious.
• Device and session review — log out unknown sessions after travel or shared PCs.
• API keys — analytics gets read-only, IP-restricted keys with withdraw disabled. API setup.

Monthly 10-minute hygiene

• Confirm 2FA device still in your possession; re-backup codes if phone changed.
• Revoke unused API keys and OAuth-style connections.
• Review recent login locations; change password if anything looks odd.
• Re-read phishing patterns — scam protection.

Separate credentials from portfolio tools

Portfolio dashboards should never ask for withdraw-enabled keys or seed phrases. Smitvi syncs read-only; your withdraw path stays on Binance with whitelist delays. Keep seeds and backup codes out of cloud notes.
