# Register your app in Twilio Verification API

For the Twilio Verification SDK for Android to receive SMS messages without requesting SMS read permissions, register your app's hash so that Google Play Services can route the SMS to your app.

This is the way Google Play Services redirects the SMS to the app without forcing it to request the `SMS_READ` permission.

To obtain your app's hash you can use this script: [sms\_retriever\_hash\_v9.sh](https://docs-resources.prod.twilio.com/documents/sms_retriever_hash_v9.sh)

Usage:

```bash
./sms_retriever_hash_v9.sh --package package_name --keystore keystore_file
```

For example

```bash
./sms_retriever_hash_v9.sh --package com.package.name --keystore ./debug.keystore 
```

The script will prompt you to input the keystore password. For debug keystores the default password is `android`

This is the transformation the script does:

Once obtained, browse to the Twilio Console -> Verify -> (application) -> Settings and add the hash in the Android SDK Hash Signature field then save it:
