# 60002: End User Identification Timeout

Log Type: TWILIO

Log Level: ERROR

## Description

You see this error when a Verify Silent Network Auth verification times out before the device completes the end-user identification step. In most cases, the device did not invoke `sna.url` within its 10-minute time-to-live.

### Possible causes

* The mobile device did not invoke `sna.url` before the 10-minute time-to-live expired.
* Your application did not complete the handoff from the Start New Verification response to the mobile device that must make the Silent Network Auth request. A mobile device with a SIM must directly invoke the URL for the flow to complete.
* In a desktop or cross-device flow, the end user did not continue the authentication step on their mobile device before the verification attempt expired.

### Possible solutions

* Start a new verification for the same phone number to generate a new `sna.url` and restart the timeout window.
* Invoke `sna.url` from the end user's mobile device over the mobile network as soon as you receive it. The URL is unique for each verification attempt and can only be processed once.
* If you start the flow on desktop, send the user to a mobile device immediately and complete the Silent Network Auth step there. You can implement this handoff with a QR code flow or an SMS link flow.
* If timeouts are common in your flow, consider using `channel=auto` so Verify can fall back to SMS when Silent Network Auth cannot be completed.
