I am new to ssh public-private keys so I followed instructions on the web.
https://www.funzi.org/2015/03/01/basic-freebsd-hardening/
When I created my keys I was asked if I wanted to create a passphrase for the private key. I picked yes.

So I see this 'passphrase' is an extra layer of security baked in. Is this a feature that everyone uses or is there specific use cases?
I used:
What is this art used for? To share my public key?
Do I really need to create RSA keys too or is ed25519 alone fine? It is the only key I am using.

ssh-keygen -t ed25519
What is this art used for? To share my public key?
Code:
The key's randomart image is:
+--[ED25519 256]--+
{SNIP}
+----[SHA256]-----+
