Two-Factor Authentication
Add an extra layer of security to your Karsilo account with two-factor authentication.
Why enable 2FA
Two-factor authentication protects your account even if your password is compromised. With 2FA enabled, logging in requires both your password and a time-based code from an authenticator app. This dramatically reduces the risk of unauthorized access to your revenue data.
Setting up 2FA
Go to Settings → Security → Two-Factor Authentication and click 'Enable'. Scan the QR code with an authenticator app like Google Authenticator, Authy, or 1Password. Enter the 6-digit verification code to confirm setup. Store the backup codes in a safe place.
Backup codes
When you enable 2FA, Karsilo generates 10 one-time backup codes. Each code can be used once if you lose access to your authenticator app. Store these codes securely — for example, in a password manager or printed in a safe location. You can regenerate codes from the security settings.
Disabling 2FA
If you need to disable 2FA, go to Settings → Security → Two-Factor Authentication and click 'Disable'. You'll need to enter a valid 2FA code or backup code to confirm. Note that disabling 2FA reduces your account security, and we strongly recommend keeping it enabled.
