What is QR code login

QR code login lets you sign in to the Stareceipt web application on any browser by scanning a code with your already-authenticated mobile app. Because the mobile app holds a valid session, the desktop session is authorised immediately — you do not need to type your password or an OTP code.

This is useful when:

You are on a shared or unfamiliar computer and do not want to type your credentials.
Your two-factor authentication device is your phone and you want a faster flow.
You want to switch between desktop and mobile without re-entering credentials.

Requirements

Stareceipt mobile app installed on your iPhone or iPad. Android support will apply to invited beta builds and later Google Play releases.
You must already be signed in on the mobile app.
The QR login session is short-lived and expires automatically. If the page says the code expired, refresh it and scan again.

How to sign in via QR code

On the browser (desktop or tablet)

Go to app.stareceipt.com.
On the sign-in page, click Sign in with QR code.
A QR code is displayed. Keep this tab open and do not refresh.

On your phone

Open the Stareceipt mobile app.
Open the in-app QR login scanner entry.
Point your camera at the QR code on the screen.
Tap Authorise in the confirmation prompt that appears on your phone.

The browser tab refreshes automatically and you are signed in.

Security details

Each QR code is single-use. Scanning it a second time has no effect.
The code encodes a short-lived token tied to your session; it does not contain your password.
If the QR code expires, click Refresh code on the sign-in page to generate a new one.
If you did not initiate the sign-in request, tap Deny on your phone instead of Authorise. Your account is not affected.
Authorising a QR code grants the same session permissions as a normal sign-in on that device.

Troubleshooting

The browser does not refresh after I scan

Check that your phone has an active internet connection.
Try tapping Authorise again if the prompt is still visible.
If the code has expired, click Refresh code and scan the new code.

I cannot find the QR scanner entry in the mobile app

Update to the latest app build and check your account menu for QR login or scan-based sign-in options. See Mobile App Guide for download links.

The camera does not open in the app

Grant camera permission to the Stareceipt app in your device settings:

iOS: Settings → Stareceipt → Camera → Allow.
Android: on an invited beta or later Google Play build, use Settings → Apps → Stareceipt → Permissions → Camera → Allow.
