Device Trust & Confirmation

DocSnap uses a device trust system to protect your account. When you log in from a new device, it must be confirmed before you can access your documents.

How Device Trust Works​

First Device​

The first device you log into after verifying your email is automatically trusted. No additional confirmation is needed -- you're logged in immediately.

Additional Devices​

When you log in from a new device (a different phone or tablet), DocSnap requires you to confirm it:

  1. Enter your email and password on the new device
  2. A confirmation email is sent to your verified email address
  3. The app shows a "Confirm Your Device" waiting screen
  4. Open the email and tap the confirmation link
  5. The new device is confirmed and you're automatically logged in

Why Device Trust?​

Device trust adds a layer of security beyond your password. Even if someone knows your password, they can't access your account from a new device without also having access to your email inbox. This protects against:

  • Stolen passwords
  • Unauthorized access from unknown devices
  • Account sharing without your knowledge

Confirming from Any Browser​

The confirmation email link works from any device or browser -- you don't need to open it on the new device. For example:

  • You can confirm a new iPad by tapping the link on your iPhone
  • You can confirm from a laptop or desktop browser
  • The DocSnap app on the new device polls automatically and will detect the confirmation

Device Identity​

Each device is identified by a unique ID that's:

  • Generated automatically when you first log in
  • Stored securely in the device's Keychain
  • Persistent across app reinstalls (tied to the device, not the app)

This means:

  • Reinstalling DocSnap on the same device won't require re-confirmation
  • Logging in on a different device will always require confirmation (unless previously confirmed)

Managing Devices​

Currently, device trust is managed automatically. Once a device is confirmed, it remains trusted until your account settings are changed.
