Can I, and in that case how can I, change the password of an SSH identity file without having to generate a new key and setting up it all over again?

Yes, it does look like it is. Is there any policy about duplicates spanning different sub forums in the stackexchange network? – lindhe Jun 10 '15 at 20:34

1No, I don't think there is. I just added that link manually for the benefit of anybody searching here for a question similar to yours. – Greg Hewgill Jun 10 '15 at 20:35

1@Invoker that's not a duplicate. This question is about changing the password for an existing key. The dupe you proposed is completely different. – terdon Jun 11 '15 at 00:54

Identity file = private key file? From the manual, (man ssh-keygen):
ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile]
The -p switch changes the passphrase of a private key file with a prompt, whereas the -P switch specifies the old password on the command line. Use one of these in interactive mode depending on the encryption algorithm and file name you have used.
ssh-keygen -p -f ~/.ssh/id_dsa
ssh-keygen -p -f ~/.ssh/id_rsa
