Understanding Two-Factor Authentication (2FA)
What Is Two-Step Verification?
Two-factor authentication (2FA) adds an extra security layer to your account. When enabled, you’ll need to provide a 6-digit temporary code alongside your password for sensitive actions like withdrawals or transfers.
How TOTP Works
Crypto.com uses Time-based One-Time Password (TOTP), which generates a unique 30-second valid code. This ensures only authorized users can perform asset-related actions.
