# Verify App (2025-10-15)

{% hint style="info" %}
**Verify App** · 2025-10-15
{% endhint %}

Try PhoneCheck, Reverse SMS and PhoneCheck + Passkeys on your device.

## What it is

The Verify App is IDlayr's native reference application that lets customers and partners run full verification flows on real devices. It demonstrates the core verification experiences — PhoneCheck (commonly known as Silent Network Authentication), Reverse SMS, and an MFA example (PhoneCheck + Passkeys) — and is intended for PoCs, demos and hands-on testing.

## Why use it

* Try real-device flows (SNA, Reverse-SMS and passkey combinations).
* Use a working example of recommended SDK integration and error handling.
* See a practical and modern MFA demo that combines network authentication and passkeys.

## Get the app

Use this short link to find the right store listing for your device:

<https://verify-app.idlayr.com/redirect/app-store>

## Key features

* **PhoneCheck (SNA)** — silent network authentication to verify the subscriber's device/number.
* **Reverse SMS (mobile-originated SMS)** — end-to-end reverse SMS flow as a fallback to SNA.
* **MFA (PhoneCheck + Passkeys)** — example multi-factor workflow combining network auth with a passkey.
* **Activity reports** — view detailed check results and share or report runs to IDlayr.

## How to try it

1. Install the Verify App from the store link above on a test device (iOS or Android).
2. Open the app and choose a flow: *Verify with SNA*, *Verify with SNA + Passkey*, or *Verify with Reverse SMS*.
3. Enter a phone number, accept terms, and follow the on-screen guidance. Try edge cases (wrong number, airplane mode, blocked mobile data) to exercise error handling.
4. Open the Activity report to inspect check ID, timestamps, status, match result and network id. Use *Report to IDlayr* if you'd like us to investigate a run.

{% hint style="warning" %}
This entry uses pre-v1 product names. In v1, **PhoneCheck** is renamed to [Secure SNA](https://docs.idlayr.com/products/number-verification/secure-sna). Reverse SMS is unchanged in name.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.idlayr.com/changelog/readme/2025-10-15-verify-app.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
