# Sandbox Yacan Locks

> Add virtual Yacan locks to your Seam sandbox workspace using these sample credentials to test your integration without real hardware.

Use the following set of credentials to add virtual [Yacan locks](/device-and-system-integration-guides/yacan-locks) to your Seam [sandbox workspace](/core-concepts/workspaces#sandbox-workspaces):

| Email Address                               | Password |
| ------------------------------------------- | -------- |
| [jane@example.com](mailto:jane@example.com) | 1234     |

During the Connect Webview flow, sign in with these credentials and authorize access when prompted. The sandbox workspace includes two virtual locks: **Front Door** (online through a gateway, so it supports remote lock/unlock and access codes) and **Back Door** (no gateway, useful for testing capability gating).
