# User + Channel Provisioning

### Network Credentials <a href="#network-credentials" id="network-credentials"></a>

Each SDK user must have a unique set of Zello Work credentials, which includes a username, password, and network name. For more information, please visit the [Network Credentials](https://sdk.zello.com/core-concepts/network-credentials) page.

### User Provisioning <a href="#user-provisioning" id="user-provisioning"></a>

User credentials can only be used on one device at a time. If two users try to access Zello Work simultaneously with the same credentials, one user will be automatically disconnected. For this reason—and because all communications are tied to a specific user— it’s best to assign each individual their own set of credentials.

Network admins can create individual user accounts from the management console—either [manually](https://paidsupport.zello.com/hc/en-us/articles/26981814818061-Adding-users-to-the-network) or via [CSV import](https://paidsupport.zello.com/hc/en-us/articles/26983665414413-Importing-new-users-and-exporting-user-data)—or by using the [Zello Work API](https://zellowork.com/api.htm).

### Channel Provisioning <a href="#channel-provisioning" id="channel-provisioning"></a>

Channels facilitate quick communication among subsets of assigned network users. Like users, channels can be created from the management console—either [manually](https://paidsupport.zello.com/hc/en-us/articles/26989198616845-Adding-and-setting-up-network-channels) or via [CSV import](https://paidsupport.zello.com/hc/en-us/articles/26989479686925-Channel-Import)—or by using the [Zello Work API](https://zellowork.com/api.htm). This ensures communications remain targeted, secure, and unified.
