What Two Factor Setup Actually Does
When you activate two factor authentication, jurnal4d requires a one-time code alongside your password at every login. That code comes either from an authenticator app — Google Authenticator and Authy both work — or via SMS to your registered mobile number. Open your account settings, go to Security, and select Enable Two Factor. Scan the QR code with your authenticator app or
enter your phone number for SMS delivery. Each code expires within 30 seconds, making replay attacks ineffective. Once active, the setting applies across all devices, including mobile access on Android and iOS, where local law and eligible regions permit.
