Sign in to LightInventory
Sign in with Google or an email and password, then confirm it's you with a passkey, an authenticator app or a recovery code.
Last updated October 30, 2026
Signing in always takes two steps. First you prove who you are with Google or with your email and password. Then you confirm it's you with a second factor: a passkey, a code from an authenticator app, or one of your recovery codes. This is the same on every plan.
Sign in
- Open the sign-in page and select Continue with Google, or enter your email and password and select Sign in.
- On the Confirm it's you screen, select Use a passkey and follow your browser's prompt.
- To use another method, select Use another method, then Use your authenticator app or Use a recovery code.
Google sign-in counts as the first factor only, never as both. Even after you sign in with Google, LightInventory asks for your second factor.
Passwords
- Use 12 to 128 characters. Spaces and any symbols are allowed, and there are no rules about mixing letters, numbers and symbols.
- Passwords are checked against lists of breached passwords. If yours appears in a known breach, choose a different one.
- Password managers and pasting work on every sign-in field.
If you forgot your password, see Reset your password.
Your first sign-in
New accounts with an email and password confirm the email address first. After that, a setup wizard asks for three things before you can use the app:
- A passkey.
- A second method: another passkey, for example on your phone or a hardware security key, or an authenticator app.
- Your 10 recovery codes, which you save before you continue.
Every user keeps at least two sign-in methods, so losing one device does not lock you out of your account. Learn more about passkeys, the authenticator app and recovery codes.

Wrong attempts and privacy
The sign-in screens never tell anyone whether an account exists for an email address. A failed sign-in says only that the email and password did not work.
After 10 failed second-factor attempts, sign-in is locked for a while. The delay starts at 30 seconds and grows up to 1 hour, and the screen shows how long to wait.
