Coinbase vs Gemini Passkey 与提现地址控制对比
本文正文暫以英文原文展示，翻譯版本需完成來源複核後再發布。
已验证事实边界
1. Coinbase says 2-step verification is required to access an account and recommends setting up multiple 2FA methods. 2. Coinbase says address-book allowlisting limits sends to addresses in the address book and a newly added address becomes available for sends after 48 hours. 3. Coinbase Exchange says API users can add or delete addresses and withdraw using whitelisted addresses, but cannot enable or disable whitelisting through the API. 4. Gemini says 2FA is required and cannot be disabled. 5. Gemini says passkeys become the default 2FA method after opt-in, and approved-address flows can require a 7-day hold or multi-user approval.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Authentication baseline | required 2FA or passkey/security-key setup | record active and backup methods | account-specific recovery state |
| Backup method | how access survives device loss | configure before changing phones | cloud sync or device-bound passkey limits |
| Address control | allowlist, whitelist, approved address or withdrawal protection | turn policy wording into a checklist | jurisdiction-specific naming |
| Waiting period | 48-hour or 7-day address availability window | add destinations before urgent need | case-specific compliance holds |
| API boundary | whether automation can change destination policy | separate UI policy from API action | product-specific API rules |
| Approval role | single-user hold or multi-user approval | name the required role without exposing identity | organization permission drift |
| Recovery trigger | lost key, lost device or suspicious address change | document support path before incident | private support result |
| Destination scope | asset, network, portfolio or account scope | check asset and network together | wrong-chain address risk |
| Evidence packet | official URL, date and non-secret configuration summary | retain without keys or codes | private balances and IDs |
| Stop rule | when the setup is not decision-quality | stop on unknown recovery, rushed address wait or broad withdraw API | future policy changes |

控制说明
1. Authentication baseline
这一项要求读者先把公开来源翻译成操作规则。这里的含义是：required 2FA or passkey/security-key setup。可执行动作是：record active and backup methods。仍然未知的是：account-specific recovery state。因此本文不会把未知部分包装成安全承诺、收益承诺、官方背书、审批保证、可用性保证或注册诱导。
2. Backup method
这里的含义是：how access survives device loss。可执行动作是：configure before changing phones。仍然未知的是：cloud sync or device-bound passkey limits。
3. Address control
这里的含义是：allowlist, whitelist, approved address or withdrawal protection。可执行动作是：turn policy wording into a checklist。仍然未知的是：jurisdiction-specific naming。
4. Waiting period
这里的含义是：48-hour or 7-day address availability window。可执行动作是：add destinations before urgent need。仍然未知的是：case-specific compliance holds。
5. API boundary
这里的含义是：whether automation can change destination policy。可执行动作是：separate UI policy from API action。仍然未知的是：product-specific API rules。
6. Approval role
这里的含义是：single-user hold or multi-user approval。可执行动作是：name the required role without exposing identity。仍然未知的是：organization permission drift。
7. Recovery trigger
这里的含义是：lost key, lost device or suspicious address change。可执行动作是：document support path before incident。仍然未知的是：private support result。
8. Destination scope
这里的含义是：asset, network, portfolio or account scope。可执行动作是：check asset and network together。仍然未知的是：wrong-chain address risk。
9. Evidence packet
这里的含义是：official URL, date and non-secret configuration summary。可执行动作是：retain without keys or codes。仍然未知的是：private balances and IDs。
10. Stop rule
这里的含义是：when the setup is not decision-quality。可执行动作是：stop on unknown recovery, rushed address wait or broad withdraw API。仍然未知的是：future policy changes。
仍需明确的未知项
- account-specific recovery state
- cloud sync or device-bound passkey limits
- jurisdiction-specific naming
- case-specific compliance holds
- product-specific API rules
- organization permission drift
- private support result
- wrong-chain address risk
- private balances and IDs
- future policy changes
实用结论
本文最有价值的地方是克制。Coinbase 与 Gemini 都把用户引向更强的认证和目的地控制，但风险包装方式不同。Coinbase 表示 2-step verification 是必需项，建议配置多个备用方法，支持 passkeys 和 security keys，并通过 address-book allowlisting 把发送限制到已保存地址；新地址通常需要 48 小时后才可用。Coinbase Exchange 文档还说明，whitelisting 只允许向 Address Book 中已有地址提现，API 用户不能通过 API 启用或关闭 whitelisting。Gemini 表示 2FA 是必需项且不能关闭，用户启用 passkeys 后它们会成为默认 2FA 方法，approved-address 或 Withdrawal Protection 流程可能要求 7 天等待期或多用户审批后地址才能用于提现。有用的对比不是抽象判断哪个品牌更安全，而是在资金移动前确认恢复方法、地址等待期、API 边界和审批角色是否已经被记录。 用户应获得一个更清楚的核验路径，而不是一个看似肯定、实则无法由公开证据承担的承诺。
