Log into the Linux server as the user you are going to use to connect with ssh. Generate the key.

ssh-keygen -t rsa -b 4096 -C "email@domain.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/user/.ssh/id_rsa.
Your public key has been saved in /home/user/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:3/dDa9R+zzDpGNt/EU9Jusj/snbKt3+B8F+ULnxXtWk email@domain.com
The key's randomart image is:
+---[RSA 4096]----+

|               ..|
|              o *|
