How to Set Up SSH on Raspberry Pi for Free?
Setting up SSH on your Raspberry Pi is a straightforward process that requires minimal technical expertise. By enabling SSH, you can remotely manage your IoT devices without needing to connect a monitor, keyboard, or mouse to your Pi. This is particularly useful for headless setups, where the Raspberry Pi operates without peripherals. Let’s walk through the steps to configure SSH on your Raspberry Pi for free.
Step 1: Enable SSH on Raspberry Pi
- Download and install the Raspberry Pi Imager from the official website.
- Flash the Raspberry Pi OS onto your microSD card using the Imager.
- Before ejecting the microSD card, create a blank file named
ssh(without any extension) in the root directory of the card. This will enable SSH on your Pi during the first boot.
Step 2: Connect to Your Raspberry Pi
Once your Raspberry Pi boots up, you can connect to it via SSH using a terminal or an SSH client like PuTTY. Use the default hostname raspberrypi.local or the IP address assigned to your Pi by your router. The default login credentials are:
- Username: pi
- Password: raspberry
After logging in, it’s highly recommended to change the default password to enhance security.
Why Should You Change the Default Password?
Using the default credentials can leave your Raspberry Pi vulnerable to unauthorized access. By changing the password, you add an extra layer of security to your IoT setup. Additionally, consider disabling password-based authentication and using SSH keys for a more secure connection.
