Why SSH Keys Are Important
SSH keys play a crucial role in securing remote IoT setups, including those involving Raspberry Pi. Unlike traditional password-based authentication, SSH keys provide a more secure and convenient way to authenticate users. They consist of a public key, which can be shared with others, and a private key, which must be kept confidential.
When using SSH keys with Raspberry Pi and remote IoT platforms, users can ensure that only authorized devices and individuals can access their systems. This reduces the risk of unauthorized access and potential security breaches. Additionally, SSH keys eliminate the need for users to remember complex passwords, making them more user-friendly.
Implementing SSH keys involves generating a key pair, adding the public key to the remote server, and configuring the Raspberry Pi to use the private key for authentication. This process is straightforward and can be completed in just a few steps, as detailed in the following sections.
