CEX Sign-In — Secure Access to Your Exchange Account

Understand the sign-in model used by centralized exchanges and practical steps to keep your account safe.

Overview

Centralized exchanges (CEX) typically use email/password sign-in paired with optional or mandatory multi-factor authentication (2FA). The exchange holds custody of account balances and must therefore be secured with strong authentication controls and vigilant account monitoring.

What happens during sign-in

  • User supplies email/username and password.
  • Server validates credentials and checks device/session state.
  • 2FA (TOTP, SMS, or hardware key) may be requested for added assurance.
  • Successful sign-in issues a session token with expiry and scope.

Good hygiene

  1. Create unique passwords per service and store in a password manager.
  2. Enable an authenticator app (TOTP) or hardware security key instead of SMS where possible.
  3. Monitor account notifications and review active sessions regularly.
