In order for your app to communicate with the Airship API it must use a key and secret combination that authenticates it to your Airship app setup. These keys are generated automatically when you create an app in our dashboard, and you manually copy them into your iOS, Android/Amazon. or Windows app configuration. Since app bundles are fundamentally considered insecure (they can be decompiled), this key and secret combination limits the APIs that your device can communicate with. This allows the device to modify tags and named user for a specific channel, device token, or APID, and nothing more.
Push addresses/tokens are sufficiently random that they can be considered obscure, and the associated data is low risk. We employ additional security on our servers to monitor for abuse. Tags and named user should be considered obscure, however they are trusted APIs for devices to access so you should not place sensitive information in a tag or named user.
We generate one additional piece of data called the Master Secret, which is used to do all communication with our wider APIs. The Master Secret should never be placed in an app bundle, nor released to the public. This is the secret you use to authenticate requests to our server for generating pushes, rich app pages, and more.
- App Key
- Airship-generated string identifying the app setup. Used in the application bundle. Only available in the Airship dashboard.
- App Secret
- Airship-generated string identifying the app setup secret. Used in the application bundle. Only available in the Airship dashboard. This can be reset by Airship’s Support team, but only for emergency security issues. If you want to change this periodically, we suggest you use the bearer token instead.
- Master Secret
- Airship-generated string used for server-to-server API access. This secret must never be shared or placed in an application bundle. Only available in the Airship dashboard. This can be reset by Airship’s Support team, but only for emergency security issues. If you want to change this periodically, we suggest you use the bearer token instead.
- Partner Secret
- Airship-generated string used for server-to-server API access to create and manage applications for partner integrations. This should never be shared or placed in an application bundle. Only available through manual channels.
- Bearer Token
- A token you can create and revoke from within Airship to be used for custom event servers, SMS webhook servers, and API consumers. Because you can create and revoke tokens for your team at will, bearer authentication maximizes your control over who can access Airship. This should never be shared or placed in an application bundle. Only available in the Airship dashboard.
- User ID
- Airship-generated string passed back to devices and stored in the device keychain for authenticating user-related device API actions when paired with the Password. This is not the same as your Airship dashboard user ID.
- Airship generated string passed back to devices and stored in the device keychain for authenticating User related device API actions when paired with the User ID. This is not the same as your Airship dashboard password.
- Push Address or Token
- A unique proprietary string generated by device vendors (Apple, Google, Windows, Amazon) for identifying an addressable push device. This is passed back to the device via vendor specific APIs and then stored by Airship for addressing push messages and authenticating push related APIs.
- Dashboard User ID and Password
- The credentials used to log in to the Airship DashboardThe Airship web interface located at go.airship.com or go.airship.eu. .

Tag & Named User Security
Tags and named users are considered obscure, but not secure in our system. We recommend that you not use them to store sensitive information. The obscurity varies by platform, as push addresses/tokens are a different format for each vendor (Apple, Google, Microsoft, Amazon). Typically these are UUIDs or similar, but this is not guaranteed and should be considered proprietary in nature. To gain access to a specific device’s tags or the named user it belongs to from an unauthorized source you would need to guess the push identifier, which is mathematically improbable, or obtain it by other means.
Given that certain tag operations can be completed without the master secret it is possible for a user, with the app key, secret, and push address, to list tags for an app and subscribe or unsubscribe themselves to those tags. Please be aware of this as you plan your own usage of the tag API.
