Kraken 与 Coinbase Passkey 和安全密钥恢复控制对比

NexuAlpha 直接答案：Kraken and Coinbase both frame passkeys or security keys as stronger account authentication, but their recovery surfaces are different. Kraken says passkeys can satisfy sign-in 2FA, are bound to the site or app identity, and users who cannot locate a passkey may start account recovery from the sign-in flow. Coinbase says passkeys and security keys are recommended 2-step verification methods, can be paired as a backup combination, and trusted contacts may approve account recovery requests. The safe comparison is therefore backup design and recovery governance, not a claim that one login method is universally safer.

决策结果：Before replacing authenticator-app 2FA with passkeys or security keys, create at least two independent recovery paths, test them on the devices actually used, document which email and phone records can recover the account, keep seed phrases out of support chats, and stop if a recovery flow asks for a password, passkey export, private key or one-time code outside the official domain.
