How do I enable two-factor authentication (2FA) on my account?

Two-factor authentication adds a second check on top of your password. Even if someone gets the password right, they cannot sign in without the second factor. Worth turning on for any account that touches billing or production data, which yours does.

Two options for the second factor

• Authenticator app (TOTP). Works with any compatible app — Google Authenticator, Authy, 1Password, Bitwarden, Microsoft Authenticator. Recommended for most people.
• Email codes. We send a 6-digit code to your account email each time you sign in from a new device. Easier to set up; slightly weaker if your email itself is compromised.

If you're not sure which to pick, go with the authenticator app. It's a one-time setup and meaningfully more secure.

Setting up the authenticator app

1. Open Account Settings → Security.
2. Click Enable 2FA. We'll show a QR code.
3. Open your authenticator app and scan the QR code.
4. The app starts generating 6-digit codes that rotate every 30 seconds.
5. Enter the current 6-digit code in our dashboard to confirm everything's wired up correctly.
6. Save your backup codes somewhere safe. These let you recover access if you lose your phone — we cannot reset 2FA without them once enabled.

After 2FA is on

Each sign-in asks for your password, then the current 2FA code. We remember devices for 30 days — same browser on the same machine won't prompt again until that window expires, or until you sign out manually.

If you lose access to your second factor

Use one of the backup codes you saved at setup time. Each backup code works once. If you have no backup codes left, contact support@validemailchecker.com from the email address on your account and we will manually verify your identity before disabling 2FA.
