Account security is usually discussed as a login problem, but active traders need to think one step further: what happens after an attacker gets inside. Coinbase’s help center describes passkeys and two-step verification for sign-in. Kraken documents separate two-factor authentication for funding actions such as withdrawals. Binance’s anti-phishing code guide shows another layer for checking whether platform emails are genuine.
The lesson is that no single control is enough. A passkey can reduce phishing and password-reuse risk, but traders still need a recovery plan if a device is lost. App-based 2FA is stronger than SMS in many cases, but it must be backed up securely. Withdrawal controls are critical because the final loss often happens when funds leave the venue, not when the password is guessed.
A practical setup has four layers: strong unique password or passkey, sign-in 2FA, withdrawal or funding 2FA where the platform supports it, and communication checks such as anti-phishing codes. API traders should also restrict keys by permission and IP address, especially when bots run from a fixed server.
Traders should review these settings before volatility, not during a panic. The worst time to discover a broken authenticator, stale phone number or unrestricted withdrawal address is after a position is already moving against the account.
