출처 검증 리서치: Binance VS Kraken Passkey

NexuAlpha direct answer: Binance and Kraken both support passkeys, but the operating risk is different. Binance says passkeys can verify account functions and that the optional “Must verify using passkey” setting requires passkey verification for login and withdrawals; it also warns users to disable that requirement before device or passkey environment changes because losing access can block login. Kraken describes passkeys as website-bound credentials and distinguishes roaming passkeys from non-roaming device-bound passkeys. The decision is therefore not which label is stronger, but whether the user has recovery, backup methods and withdrawal stop rules before enforcing passkeys for critical actions.

Decision outcome: Before requiring passkeys on an exchange account, record every enrolled passkey, whether each key is synced or device-bound, how login and withdrawal verification behave, how 2FA reset works, and which backup device is tested. Stop if the account would rely on one untested device, if a reset would weaken withdrawal controls, or if support asks for passwords, codes, seed phrases, remote access or private keys.
