## Sign-In Issues

| Issue                        | Resolution                                                                                                                |
| ---------------------------- | ------------------------------------------------------------------------------------------------------------------------- |
| Unable to sign in with email | Verify your email address and password, then try again.                                                                   |
| Forgot password              | Use **Forgot password?** on the password screen to reset your password. A reset email is sent to your registered address. |
| SSO authentication fails     | Verify your organization domain and complete any required MFA prompts.                                                    |
| PIN expired                  | Select **New PIN** to generate a new PIN, then complete the pairing process before it expires.                            |
| PIN pairing unsuccessful     | Confirm that the PIN was entered correctly in the Frontline Portal under **Profile > Pair Device**.                       |

## QR Code Not Detected

If the QR code is not detected during anchoring:

* Adjust your viewing angle or move closer (30–90 cm / 1–3 ft works best).
* Ensure the QR code is fully visible, well lit, and free of glare or reflections.
* Confirm the **QR Code Size** setting matches your printed code — see [Settings](/frontline/ipad/reference/settings).

For the full anchoring workflow, see [Anchor with a QR Code](/frontline/ipad/operate/anchor-with-qr).
