Add the new-address lock if you want a 24-hour delay before withdrawals to newly added recipients. These settings reduce different risks; none guarantees that an account or funds cannot be compromised.
This guide covers the OKX exchange account, not the separate OKX Web3 self-custody wallet. Menu labels and availability may vary by app version, platform, region, and account eligibility, so use the options shown in your logged-in account.

What each OKX security control does
| Control | What it protects | What it does not replace |
|---|---|---|
| Passkey | Authenticates account access using a FIDO credential, which can rely on device biometrics or PIN, another device, or a compatible USB security key. | Withdrawal destination controls. |
| Authenticator-app 2FA | Adds a verification step beyond the account password. | A strong unique password, passkeys, or checking withdrawal destinations. |
| Withdrawal allowlist | Restricts withdrawals to recipients saved in the withdrawal address book. | Recipient verification, which remains a separate setting. |
| New-address lock | Delays withdrawals to newly added allowlist recipients for 24 hours. | Careful review of addresses and networks before saving them. |
OKX describes passkeys as a FIDO authentication method and recommends authenticator-app 2FA alongside a strong, unique password, an anti-phishing code, and connected-device management. See OKX’s passkey setup guide and account-security guidance.

Choose a method you can continue to access. Depending on your device and platform, you may use device biometrics or PIN, approve with another phone or tablet, or use a FIDO2-compatible USB security key. OKX documents the security-key category as an optional setup method; it does not establish that a particular model works with every device.

Requirements and labels above come from OKX’s web passkey instructions and app passkey instructions, updated in August 2026. OKX says at least one passkey must remain linked after the feature is activated. If changing phones, establish and test a working replacement before removing the old credential. Removing a passkey without verifying the removal with another passkey may trigger a 24-hour restriction on withdrawals and P2P trading.

OKX’s security guidance recommends enabling 2FA with an authenticator app. The exact in-account route can vary, so follow the security prompts displayed for your account rather than relying on a menu path that may differ by version or region. Keep access to the authenticator available and complete the verification steps OKX presents.

- Use a strong, unique password. Do not reuse a password from another service.
- Set an anti-phishing code. Use it to help check whether emails claiming to come from OKX are legitimate.
- Review connected devices. Remove devices you no longer recognize or use.
- Review other security settings periodically. Include passkeys, authenticator binding, API permissions, and withdrawal settings.
These measures are layered defenses: a sign-in factor does not verify that a withdrawal recipient is the intended one.

Save legitimate recipients carefully before turning on the restriction. Confirm the destination address and the network for each recipient; an address or network error can still result in a failed or misdirected transaction.

- In the OKX app, open Assets > Withdraw > Withdraw crypto.
- Open Address book, then Address settings.
- Enable the withdrawal allowlist so withdrawals can go only to recipients saved in the address book.
- If you want a delay on new recipients, enable the new-address withdrawal lock as well. Newly added recipients cannot be used for withdrawals for 24 hours.
OKX documents these app steps in its withdrawal allowlist instructions, updated in September 2026. The lock gives you time to notice and respond if an unauthorized address is added; it is a delay, not a guarantee against loss.
Web address-book details
OKX’s web guidance describes the same core restriction and the 24-hour lock for newly added allowlist addresses. It says web users can add up to 50 addresses in one batch and states no total cap. These are operational details in OKX’s web allowlist instructions, updated in August 2026.

Allowlisting is separate from recipient verification
An address saved in the allowlist may still require additional recipient verification. Do not treat the address book as an exemption from other checks. OKX also requires security verification to disable allowlisting; after it is disabled, a recipient can be entered manually during withdrawal.
Respond to a suspected account compromise
If you suspect someone else has access, review the authenticator binding, passkeys, withdrawal whitelist, API permissions, and active devices. Remove unrecognized credentials or devices and reset a compromised password. OKX’s account-security checklist covers these review areas; use the security options available in your account.
