| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Phishing marker | custom code or phrase shown in official communications or login surfaces | set it and verify before clicking links | localized delivery behavior |
| Passkey dependency | whether passkey setup requires another authenticator | document recovery before enabling passkey | device compatibility |
| Withdrawal confirmation | extra approval before a withdrawal proceeds | test with no-value or smallest safe workflow | mobile-device loss |
| Cancellation window | whether a just-started withdrawal can be cancelled | know the time window before funds move | asset-specific timing |
| Login IP control | restriction or reaction when login IP changes | avoid enabling without travel or VPN plan | dynamic IP effects |
| Official verification | tool for checking domains, contacts or media identities | verify the contact before support action | database freshness |
| Security-change hold | temporary withdrawal pause after account changes | plan changes before urgent withdrawals | account-specific flags |
| Credential boundary | what must never be shared | never disclose codes, passwords, keys or passphrases | support impersonation |
| Evidence packet | official URL, date and non-secret setting names | save only non-sensitive proof | private account status |
| Stop rule | when comparison cannot support action | stop if the domain, security setting or withdrawal state is unclear | future feature changes |

实用结论
本文最有价值的地方是克制。Bitget 与 KuCoin 都公布了账户安全控制,但它们解决的操作问题并不完全相同。Bitget 表示,用户可在设置 Google Authenticator 后设置 passkey,使用 fund code 与 PIN code,设置 anti-phishing code,并开启 cross-device withdrawal verification;该提现验证要求网站提现请求在手机端确认后才会批准,且 cancel-withdrawals 默认开启,允许短时间取消。KuCoin 表示,用户应限制登录 IP,设置用于邮件、登录和提现码的 anti-phishing safety phrase,使用 Official Verification Center 核验联系人或域名,并在某些账户安全变更后预期 24 小时提现暂停。决策重点应是控制覆盖,而不是笼统的安全标签。 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。
