Use an authenticator app with LightInventory

Add an authenticator app as a sign-in method and enter its 6-digit code when you sign in. Each code changes every 30 seconds and works once.

Last updated October 30, 2026

An authenticator app on your phone shows a 6-digit code for LightInventory that changes every 30 seconds. You can use it as your second sign-in method next to a passkey. Passkeys stay the default, because they resist phishing and codes do not.

Add an authenticator app

  1. Open the Account menu and select Security.
  2. Select Add an authenticator app and confirm it's you with a fresh second factor.
  3. Scan the QR code with your authenticator app. If you cannot scan it, select Copy key and enter the key in the app instead.
  4. Enter the 6-digit code the app shows and select Confirm.

You can also add the app as your second method in the setup wizard during your first sign-in.

Sign in with a code

  1. Sign in with Google or with your email and password.
  2. Select Use your authenticator app.
  3. Enter the current 6-digit code for LightInventory.

Each code works only once. If a code was already used, wait for the next one. If a code does not work, check that your phone's clock is set automatically, then try the current code.

How the secret is protected

The app and LightInventory share a secret that creates the codes. We store it encrypted, with an extra layer of encryption from keys held in a key management service, as explained on the security page.

Owners and Admins

Organizations and roles arrive in a later release. When they do, Owners and Admins must use phishing-resistant sign-in by default, so authenticator apps are turned off for those roles unless the Owner changes the setting. See Passkeys.
