Setting up an OKX passkey and keeping a second sign-in method you can rely on
How to add a passkey to your OKX account from the security center, choose where the passkey is stored, and keep an authenticator app as backup so a lost phone does not lock you out.
OKX | Italy | EUR | fees, access and account safety
A passkey lets you sign in to OKX with your phone's fingerprint, face unlock or screen lock instead of typing a password. Because it is tied to the real OKX domain, a lookalike phishing page cannot use it. That makes it one of the strongest login options available. The catch is that a passkey lives somewhere: on one device, or in a synced password manager. Before relying on it, decide where it lives and what your fallback is.
Add the passkey in the security center
Open the OKX app, tap your profile, then Security. Look for the passkey option and choose to add one. You will confirm with your existing method, usually an authenticator code and an email code. Your phone's system then asks where to save the passkey: on the device, in iCloud Keychain on an iPhone, or in Google Password Manager on Android. A synced option survives a phone change more easily. Shared family tablets are a poor place for a passkey, because anyone who can unlock the tablet can then sign in to your account.
Keep the authenticator app as a backup
Do not remove your authenticator app after adding a passkey. OKX still uses it to confirm sensitive actions, and it is your way back in if the passkey becomes unavailable. When you first set up the authenticator, save the setup key on paper in a safe place. If you never did, consider resetting it now while you still have access, so you can record the key properly.
Test before you depend on it
Log out, then sign in again using the passkey only. If it works on your phone, try the web login on your computer, where OKX may offer to use the phone through a QR code. Name each passkey clearly in the security center, such as personal phone, so you can remove the right one later. If any step fails, keep using the authenticator until you understand why. Repeat the test after any operating system update, since updates occasionally change how saved passkeys are offered in the browser.
Changing or losing a phone
When you get a new phone, sign in to OKX on it, confirm the synced passkey works or create a new one, move your authenticator accounts, and only then reset the old device. Afterwards, delete the old phone's passkey and check the device list in Security. If a phone is lost, remove its passkey from another logged-in device as soon as possible.
