Generate a new key on your computer
To create a new SSH key, you can do so through the command line tool on a Linux machine (or using the Windows Subsystem for Linux)
Enter the following command to create a key:
ssh-keygen -t ed25519 -C "[email protected]"
In this example, the ssh-keygen command creates a new SSH key using the Ed25519 algorithm.
The -C option adds a comment to the key, which is your email address in this case. The command will prompt you for a file in which to save the key, or accept the default location.
