Registering a second OKX passkey on a separate device
Passkeys make signing in to OKX faster and resistant to phishing, because they only work with the genuine site or app and there is no code to type into a fake page. But if your only passkey lives on one phone, losing or replacing that phone can leave you working through account recovery at an inconvenient moment. A second passkey on a separate device, such as a tablet, a laptop or a hardware security key where supported, removes that single point of failure. This guide helps readers in Italy register and manage a second passkey on OKX. Supported devices and menu names may change, so follow the OKX help centre.
Choose the second device
Pick a device that is unlikely to be lost or damaged at the same time as your phone. A laptop kept at home or a security key stored separately are common choices. Check how passkeys sync on each device: a passkey that syncs through the same cloud account as your phone may not protect you if that cloud account itself becomes inaccessible. A truly separate device adds more resilience.
Register it while you are signed in
Sign in to OKX on your primary device, open the security settings and add a new passkey following the prompts on the second device. Give each passkey a clear name, such as phone or home laptop, so that you can tell them apart in the list. Do this on a calm day, not while travelling or in the middle of a trade, so you can complete each step without pressure.
Test both
After registering, sign out and sign in again using the second device to confirm that its passkey works. Then do the same with the first. A passkey that has never been tested is only an assumption. Write down in your private security notes which devices hold passkeys and when you last tested them, without recording any secret information.
Keep the list tidy
Review the passkey list in your security settings every few months. Remove any passkey for a device you no longer own or have reset. If a device is lost or stolen, remove its passkey promptly from another signed-in device and review recent account activity. Treat any message asking you to approve a passkey you did not create as suspicious, and report it through the official app.

Digital assets are volatile and derivatives can amplify losses. This website has no login, wallet connection, deposit form or customer-support chat. A referral link only records attribution; it does not guarantee access, pricing, rewards, approval or investment results. Availability can differ by residence, legal entity and product, so no regional access is assumed from language or branding alone.
