# Lost Your Authenticator App?

Lost your phone, replaced it, or accidentally deleted your authenticator? Use a recovery code to sign in. The code disables two-factor authentication on your account so you can re-enroll on your new device.

## What You'll Need

- One of the 8 recovery codes you saved when you set up two-factor authentication. They look like `A1B2-C3D4-E5F6-G7H8`.

## Step-by-Step

1. Sign in with your email and password as usual.
2. On the two-factor screen, click **Use a recovery code**.
3. Type one of your recovery codes (dashes optional, case-insensitive) and submit.
4. kiku does four things at once:
   - Marks that recovery code as used (it can't be reused).
   - Removes your old authenticator setup.
   - Signs you out of every active session, on every device.
   - Sends you back to the sign-in page.
5. Sign in again with just your password. You're back in.

## Setting Up Again

Once you're back in, kiku will prompt you to set up two-factor authentication again on your new device. Follow the [setup guide](https://heykiku.com/help/setting-up-2fa) and save the new recovery codes that appear — your old ones no longer work.

## Out of Recovery Codes

If you've used all 8 recovery codes and still can't sign in, contact your workspace owner. They can ask kiku support to verify your identity and reset your two-factor setup. We can't reset it for you over chat — that would defeat the point.

## What Doesn't Happen

- Your password isn't reset.
- Your workspace data is untouched.
- Other people on your team aren't signed out — only your sessions.

Recovery is a one-shot reset, not an emergency back door.
