When connecting to a server with ssh if there is a public key/private key authentication token between server, the ssh will try to use that key. If for some reason the key does not work, then ssh will try asking for a password. Key based authentication won't work if the .ssh directory is world or group writable, readable or executable or the home directory is world writable. You may want to check the permissions on your home and .ssh directories.

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be
enabled, unless you've done some clever use of multiple identities)
It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth-
erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration).
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary)
