Two-Factor Authentication
2FA adds a second proof-of-possession requirement. Prefer authenticator apps (TOTP) or hardware keys (WebAuthn/U2F) over SMS to reduce SIM-swap risk.
1
Enable TOTP
Scan the QR with an authenticator app and securely store printed backup codes.
2
Consider hardware keys
Hardware keys provide phishing-resistant authentication — ideal for large balances.
3
Device management
Name trusted devices and remove any you don't recognize from account settings.
Backup & recovery
Store recovery codes offline and keep a plan for lost 2FA devices (backup codes, additional hardware key). Test recovery steps ahead of time if possible.
