Exchange security is not just a setup task during registration. Coinbase’s security guidance tells users to check email settings and authorized devices, Kraken explains where signed-in devices can be reviewed and deactivated, and OKX highlights 2FA, anti-phishing codes, device review and withdrawal-address limits as account-protection tools.
The trading reason is straightforward: a compromised account can become a trading loss before it becomes a withdrawal loss. An attacker may open leveraged positions, change risk settings, or create API access even when withdrawals are delayed. If a new-device alert appears, the first step is not to rush into the market. It is to open the official app or bookmarked site directly, review active sessions, revoke unknown devices, rotate passwords, and confirm that authenticator-based 2FA is still under your control.
A practical checklist is: do not click login links inside the alert email; verify the anti-phishing code when the exchange supports one; review notification settings; check withdrawal allowlists; inspect recent orders, API keys and funding transfers; then wait before using futures again. Traders who run bots should also review IP restrictions and trading-only permissions.
