Security checklist

- ⚠️ Activate more than one 2FA method if possible.
- ⚠️ Avoid SMS unless as last resort.
- ⚠️ Reset your 2FA when changing phones.
- ⚠️ Store your FIDO2 key in a safe but accessible place.
- ⚠️ Review settings annually.
Common mistakes and how to avoid them
- Relying only on SMS → vulnerable to SIM swap. Prevention: use Authenticator or FIDO2.
- Losing phone without backup → locked out. Prevention: store codes offline.
- Not testing before logging out → blocked access. Prevention: always verify with a test code.
Practical examples
- A user relying only on SMS loses access after SIM swap.
- Another with Authenticator recovers thanks to properly stored backup codes.
Quick comparisons

Frequently asked questions
What is 2FA and why do I need it?
Two-Factor Authentication adds a second step, making your account much harder to compromise.
What 2FA options does Binance offer?
Google Authenticator, SMS (less secure), or hardware keys like FIDO2/U2F.
Is SMS 2FA secure?
It’s better than nothing, but vulnerable to SIM swap attacks. Authenticator or FIDO2 are safer.
What if I lose my phone with the Authenticator app?
Use your backup codes to restore access. That’s why offline backups are essential.
What are FIDO2/U2F keys?
Physical devices that generate unique codes. They provide the strongest anti-phishing protection.
Can I activate multiple 2FA methods?
Yes, for example Authenticator plus a FIDO2 key as a backup.
Where should I store my backup codes?
On paper or a metal plate stored securely. Never in email or cloud services.
What happens if I don’t enable 2FA?
Your account stays vulnerable. Anyone with your password could access and move funds.
How long does setup take?
Less than 5 minutes, just follow Binance’s instructions.
How often should I review my setup?
At least once a year or whenever you change devices.
