TLDR: Thirdfort uses your device's back camera to verify documents. If your camera is broken, you must use another device to complete the check. Install the app on the new device and sign in with your mobile number if not signed in before. If already signed in, contact the requesting company or Thirdfort Support to reset access and switch devices.
Broken Camera
If you have been asked to provide your ID, or want to photograph a document to upload as your proof of address or ownership, Thirdfort uses the back camera of your device.
If your device's camera is broken or is unable to take a suitable photo for Thirdfort to verify your document, you will be unable to complete your check on that device.
Using another device
If you have access to another device, such as a work phone, or a friend/family member's device, you can instead use this to complete your check.
I've not signed in, how do I use another device?
If you have not signed into the app, you can install Thirdfort directly onto the app you want to use from the Apple App Store or Google Play Store. The link in your invite text is not specific to your check.
When signing in, you will be asked for a mobile number. You will need to enter your number on the alternative phone to receive your code and sign in to your check.
I've already signed in, how can I swap to another device?
If you have already signed into the Thirdfort app, your check is now linked to that device and cannot be accessed on another device.
To use another device, please contact the company that requested your Thirdfort check, and they can reset this on your behalf, allowing you to sign in on a new device. Alternatively, if you contact Thirdfort Support, we can request this from the company on your behalf.
