# Programming Salto Space Mobile Credentials

You can create mobile credentials that enable your mobile app users to unlock entrances in your [Salto Space access system](https://docs.seam.co/latest/device-and-system-integration-guides/salto-proaccess-space-access-system). For each Salto Space user, you can create a maximum of one [key card credential](https://docs.seam.co/latest/device-and-system-integration-guides/salto-proaccess-space-access-system/programming-salto-space-card-based-credentials) and one mobile key credential. For more information about Seam mobile keys, see [Mobile Access](https://docs.seam.co/latest/capability-guides/mobile-access).

To use the Seam API to create mobile credentials for mobile app users in a Salto Space access system:

1. Create a [user identity](https://docs.seam.co/latest/api/user_identities).

   Seam user identities enable you to match your own mobile app users to access system users that you create using the Seam API.
2. Create an [access system user](https://docs.seam.co/latest/capability-guides/access-systems/user-management) on the Salto Space access system or assign an existing access system user to the user identity.\
   The resources that you create for the access system user are available under the associated user identity.
3. Assign the access system user to one or more [access groups](https://docs.seam.co/latest/capability-guides/access-systems/user-management/assigning-users-to-access-groups).
   * Each access group is preconfigured with the allowed entrances.
4. Create a [credential](https://docs.seam.co/latest/capability-guides/access-systems/managing-credentials) to represent the mobile key.
   * Specify the ID of the access system user.
   * Set [`is_multi_phone_sync_credential`](https://docs.seam.co/latest/capability-guides/mobile-access/issuing-mobile-credentials-from-an-access-control-system#what-are-multi-phone-sync-credentials) to `true`.
   * Set the `access_method` to `mobile_key`.

The following example walks you through this process:
