​
Enable two-factor authentication

1

Open your Profile settings

Go to app.valendata.com and navigate to Settings → Account.
2

Start the 2FA setup

Click Enable Two-Factor Authentication. Valendata displays a QR code tied to your account.
3

Scan the QR code

Open your authenticator app, add a new account, and scan the QR code. Your app will immediately begin generating 6-digit codes that rotate every 30 seconds.
4

Confirm with a verification code

Enter the current 6-digit code from your authenticator app into the confirmation field and click Verify. This confirms that your app is correctly paired.

​
Sign in with 2FA enabled

After entering your email and password on the login page, Valendata prompts you for your 6-digit TOTP code. Open your authenticator app, copy the current code, and enter it to complete sign-in. Codes are valid for 30 seconds — if one expires before you submit it, simply use the next code that appears.

​
Disable two-factor authentication

You can turn off 2FA at any time from the same settings panel.
  1. Go to Settings → Account.
  2. Under the Two-Factor Authentication section, click Disable.
  3. Enter a current 6-digit code from your authenticator app to confirm your identity.
  4. 2FA is immediately removed from your account.
Disabling 2FA means your account is protected by your password alone. Re-enable it as soon as possible if you disable it temporarily, for example when switching authenticator apps.

​
Switching authenticator apps

If you move to a new authenticator app or a new device, disable 2FA first using your current app, then re-enable it and scan the fresh QR code with your new app.

Frequently asked questions

No. API keys authenticate machine-to-machine requests directly and are not subject to 2FA. 2FA only applies to interactive sign-in through the web app. Keep your API keys secure and rotate them regularly — see the API Keys guide for best practices.
Valendata does not store information about which app you use — only the TOTP secret is stored. You can disable and re-enable 2FA at any time to rotate the secret and re-pair a new app.
Two-factor authentication was introduced in Valendata v1.0.1 (released 2026-06-25).
