Account security should be set before a trader moves meaningful balances, not after the first suspicious login alert. Kraken describes passkeys as a way to satisfy sign-in two-factor authentication using device biometrics or a screen lock, while OKX documents passkey creation through its web security center. Coinbase also emphasizes strong passwords and two-factor authentication as core login controls.
A practical setup sequence starts with the device. Update the phone and browser, secure the device with a strong screen lock, and make sure the recovery email is protected by its own authenticator or hardware key. Then add a passkey or security key inside the exchange security settings, keep at least one backup method, and store recovery codes offline if the platform provides them.
The trade-off is convenience versus recoverability. A passkey can reduce phishing risk because there is no one-time code to type into a fake website, but losing the only enrolled device can create account-recovery friction. That is why larger accounts should use multiple approved methods, such as a device-bound passkey plus a separate hardware key or authenticator app, instead of relying on SMS alone.
Before sending larger funds, test the full flow with a small balance: log out, sign back in, confirm withdrawal and security-change prompts, and check whether the platform enforces cooling-off periods after security updates. If a passkey or 2FA change temporarily disables withdrawals, discover that before a volatile market session rather than during one.
