Adding a passkey in the OKX app while keeping a backup way to sign in
A passkey lets you log in to OKX with your phone's fingerprint or face unlock and cannot be phished by a fake site. Where to add it in the app, how syncing works and which backup to keep for the day the phone is gone.

Typing a password and a six-digit code every time you open the OKX app is tedious, and both can be stolen by a convincing fake login page. A passkey replaces that routine with a fingerprint or face scan, and because the key is bound to the real OKX domain, a lookalike site cannot use it. Setting one up takes a minute. The part that deserves more thought is the backup, because a passkey lives on your devices, and devices get lost.
Where the setting lives in the app
Open the OKX app, tap your profile icon and go to Security. Look for the Passkeys entry and choose to add one. Your phone will ask for its biometric or screen lock, then confirm that the passkey was saved. On iPhone it is stored in iCloud Keychain and on Android in Google Password Manager, unless you have chosen another password manager as the default. Sign out and sign back in with the passkey to confirm it works before relying on it.
Understand where the passkey syncs
Because the passkey is saved in your Apple or Google account, it may appear on other devices signed in to that account, such as a tablet or laptop. That is convenient, but check whether any of those devices are shared with family members or colleagues. For logging in on a computer without storing the passkey there, the OKX website can show a QR code that you scan with your phone to approve the login.
Keep your authenticator as a second line
Do not remove the authenticator app from OKX once the passkey works. Withdrawals and sensitive changes may still ask for an authenticator code, and the authenticator is your route back in if the passkey is unavailable. Write the authenticator's backup key on paper when you set it up and keep it somewhere safe and separate from the phone. If you lose the phone, that backup is what lets you restore codes on a new one quickly.
When you change or lose your phone
Before switching phones, make sure your Apple or Google account is signed in on the new device and that the passkey is available there, then open the OKX app and test it. If the old phone is lost, sign in from another device and remove its passkey and active session from the Security page. If you cannot sign in at all, use the option on the login screen for an unavailable security method and follow the identity checks described in the OKX help center.

Scenario checkpoint
- Add the passkey from Profile and Security in the OKX app and test a fresh sign-in with it.
- Check which tablets or computers share your Apple or Google password storage.
- Keep the authenticator app enabled and store its backup key on paper away from the phone.
- Remove a lost phone's passkey and session from another device, or use the reset option on the login screen.
