# Step 3: Client Login

{% hint style="info" %}
To ensure maximum security and optimal performance, you should create a unique user for each To ensure maximum security and optimal performance, you should create a unique user for each device you onboard. We provide [bulk automation scripts](https://docs.zmanda.com/automation-tools/bulk-operations-with-zpat) that allow you to automatically create users, install agents, register devices, and configure backup jobs for ***thousands*** of devices at once, often in just minutes. For more information, see the hyperlinked article above, or contact us at [sales@zmanda.com](https://www.zmanda.com/contact-sales/)
{% endhint %}

After successfully installing the Zmanda Pro agent, you must log in using the user credentials you created in [Step 1](/start-here/step-1-adding-a-user.md). This can be done directly on the device or remotely from the Zmanda Pro administrative portal.

### Remote Log In

Remote login is possible by using a special flag during installation. When using this flag, devices are temporarily staged in an unregistered state, after which administrators can remotely log in to the devices.&#x20;

#### Windows

Windows devices may be placed in lobby mode using the following commands:

```
cd "C:\Program Files\Zmanda Pro"
backup-tool.exe login join-lobby <your-server-url>
```

#### Linux

Before installation, Linux devices may be placed in lobby mode using the following command:

```
./ZmandaPro-xx.x.x.run --lobby
```

After installation, to join lobby mode, run:

```
/opt/ZmandaPro/backup-tool login join-lobby <your-server-url>
```

#### macOS

Run the following script, making sure to include your server's URL instead of the placeholder shown below:

```
# Silently install the client software -
sudo /usr/sbin/installer -allowUntrusted -pkg "Zmanda Pro.pkg"  -target /

# Join the remote registration lobby -
# This is not a persistent connection and will NOT auto reconnect after a client restart
"/Applications/Zmanda Pro.app/Contents/MacOS/backup-tool" login join-lobby "https://<your-server-url>.com/"
```

#### Scripts

We provide pre-built installation scripts that streamline the installation and execution of these commands. To get the scripts, free of charge, email <sales@zmanda.com>

#### Register Devices

Click the Register button and use the desired user credentials to log in to the device remotely.&#x20;
