If you don't want to use a password and security is not important, another solution is to use sshpass.

This is generally not a good idea, specially in secure environments, but in some situations it can help.

sshpass -p raspberry ssh pi@192.168.0.145

this can be combined with

ssh -q -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no pi@192.168.0.145

to avoid confirmation questions that prevent automated scripting from happening.

Again, only use this in development systems where different machines share an IP and security is not important.
