How to increase security level on OKX account?

Enable Two-Factor Authentication

1. Log into your OKX account and navigate to Account → Security Center.

2. Locate the Two-Factor Authentication (2FA) section and click Enable.

3. Choose between Google Authenticator, Authy, Microsoft Authenticator, SMS verification, or hardware keys like YubiKey.

4. Scan the QR code with your chosen authenticator app and enter the generated six-digit code to confirm setup.

5. Save the backup recovery codes in a secure offline location—these are the only way to regain access if your 2FA device is lost or compromised.

Activate Withdrawal Address Whitelist

1. Go to Security Center → Withdrawal Address Management.

2. Click Add Address and paste the intended cryptocurrency wallet address.

3. Confirm the addition using your 2FA code or hardware key.

4. Set the whitelist as mandatory for all withdrawals—any withdrawal attempt to an unlisted address will be automatically blocked.

5. Review and update whitelisted addresses periodically, especially after acquiring new cold wallets or changing custody solutions.

Configure Login Device Management

1. Access Security Center → Login Device Management.

2. View all currently active sessions including device type, OS version, IP geolocation, and last login timestamp.

3. Terminate suspicious or unrecognized sessions immediately with one click.

4. Enable “Trusted Devices Only” mode to restrict future logins exclusively to previously approved devices.

5. Manually remove outdated devices such as old phones or decommissioned laptops to reduce attack surface.

Use Hardware Security Keys

1. In Security Center, select Hardware Key under Advanced Security Options.

2. Insert your YubiKey or Titan Security Key into a USB port or tap it near an NFC-enabled device.

3. Follow on-screen prompts to register the key—this binds cryptographic identity directly to physical hardware.

4. Assign the key to critical actions: login, fund withdrawal, API key creation, and 2FA fallback.

5. Store backup keys in separate physical locations—never keep multiple keys in the same place.

Leverage OKX Protect AI Monitoring Tools

1. Ensure your account is opted into real-time transaction monitoring via Eagle Eye and SkyNet AI models.

2. Monitor alerts delivered through OKX app push notifications or email when anomalous behavior is detected.

3. Review flagged activity logs in Security Center → Risk Detection History to assess false positives or genuine threats.

4. Adjust sensitivity thresholds for transaction pattern recognition based on your typical trading volume and frequency.

5. Cross-check chain-level activity using embedded blockchain explorers for any flagged withdrawal or deposit.

Frequently Asked Questions

Q1: Can I use both Google Authenticator and SMS 2FA simultaneously on OKX?OKX allows only one active 2FA method at a time. Enabling a new method automatically disables the previous one.

Q2: What happens if I lose my hardware key and haven’t saved backup codes?Account recovery becomes impossible without verified identity documents and additional manual verification steps coordinated with OKX support—process may take up to 72 hours.

Q3: Does OKX store private keys for wallets created within its platform?No. OKX does not hold or manage private keys for self-custody wallets such as OKX Web3 Wallet. Users retain full control over their seed phrases and signing operations occur locally.

Q4: Are whitelisted addresses validated against known scam contracts before approval?Yes. OKX cross-references each submitted address against internal threat intelligence feeds and public blockchain blacklists before allowing whitelisting.
