Let’s look at the four easy steps to connect both and make them work seamlessly. The process is easy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\"\"\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t

1. Make sure you're using the latest version of Raspberry Pi OS<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

In this first step, start with two things. First, make sure you\u2019re using the latest version of Raspberry Pi OS. You can use a micro SD card and the Raspberry Pi Imager tool<\/a> to upgrade to the newest version, should you need to. Though, make sure that you\u2019ve backed up your data beforehand.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\"\"\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Or you can update the packages running on your device by running the following two commands at the command prompt:<\/p>

Terminal $<\/p>

sudo apt update<\/em>
sudo apt upgrade<\/em><\/p>

Next, you\u2019ll need to connect the Pi to a monitor or TV, which will require an internet connection.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t

2. Set up RealVNC Server on your Raspberry Pi<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

As you might know, RealVNC Server comes preinstalled on Raspberry Pi. This convenience is why enabling it is easy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\"\"\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

To do this, run the following command:<\/p>

Terminal $\u00a0<\/p>

sudo apt install realvnc-vnc-server realvnc-vnc-viewer<\/em><\/p>

RealVNC is disabled by default on your Raspberry Pi device; however, you can easily enable it using either the desktop or the terminal.<\/p>

To enable RealVNC on the desktop, navigate to the start menu > Preferences > Raspberry Pi Configuration.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\"How\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Then select \u2018Interfaces\u2019, and click \u2018Enable\u2019 next to VNC. Then click \u2018OK\u2019.<\/p>

To enable VNC using the terminal, enter the following command:<\/p>

Terminal $<\/p>

sudo raspi-config<\/em><\/p>

Using the arrows, navigate to \u2018Interfacing Options\u2019 > \u2018VNC\u2019, then choose \u2018Yes\u2019 and select \u2018OK\u2019.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\"\"\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Once you\u2019ve completed the whole process, your Raspberry Pi should appear in the list of devices in VNC Viewer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

3. Configure the resolution<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The third step depends on how you use your Raspberry Pi. Accessing software with a single window requires only more resources. However, if you use the machine to access various media, like me, you may want it to run in Full HD resolution.<\/p>

Either way, changing the resolution is not difficult. In your Raspberry Pi menu, go to\u00a0Preferences > Raspberry Pi Configuration<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t

4. Disconnect your display and use your headless Raspberry Pi<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Once rebooted, you can disconnect whichever display you were using. Once you’ve confirmed that, you can get to the Pi. And that’s it.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

End-to-end encryption helps even if someone intercepts the communication between your Raspberry Pi and your device. Without the encryption keys, the data would be unreadable.<\/p>

Also, the encryption is applied as soon as a connection is established and remains active for the duration of the session, offering continuous protection.<\/p>

This feature is particularly crucial when accessing your Raspberry Pi over public or unsecured networks, as it safeguards sensitive information like passwords and configuration settings.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

To strengthen account security, RealVNC Connect supports two-factor authentication (2FA). This feature requires a second verification step beyond the standard password, adding an additional layer of protection.<\/p>

Once you enter your password, you\u2019ll need to provide a code sent to your trusted device or email. This ensures that even if your password is compromised, unauthorized users cannot gain access without the second factor.<\/p>

RealVNC makes enabling and managing 2FA straightforward, giving you peace of mind without added complexity. When you require a combination of something you know (password) and something you have (verification code), 2FA significantly reduces the risk of unauthorized access.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
