Always being asked for passphrase

Question

I have set up an RSA keypair using

How do I set up SSH so I don't have to type my password?

But I keep getting prompted for the passphrase

Enter passphrase for key '/var/www/.ssh/id_rsa':

It never saves the passphrase?

Answer 1

ssh-keygen will ask you to enter a passphrase. At this point, just press enter. Press enter again to confirm the empty passphrase. If you don't specify a passphrase here, you won't be asked for it when you login.

# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_rsa): [just press ENTER here to save in the default location]
Enter passphrase (empty for no passphrase):                   [just press ENTER here to save your key without a passphrase]
Enter same passphrase again:                                  [just press ENTER here to confirm the empty passphrase]
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:
53:4d:b5:72:46:c1:b8:cd:72:82:3e:7a:08:f5:31:e3 user@host
The key's randomart image is:
