Way to automatically enter in shell password?

So I have a script that ssh into another computer. Since I use it often, I was wondering if I could have the script automatically enter in the password prompted by ssh, or in any other way bypass copy-pasting the password every single time I run the script?

It may be better to have a passphrase-less private key on the client side, paired with a public key in the server-side authorized_keys file with a specific command that gets run.

For example, having the following in .ssh/authorized_keys2 for the given user on the remote host:

command="date" ssh-rsa AAAAB3NzaC1yc2EAAAABIw[...]Q== Comment for passphraseless key

Will only ever run date when you connect using that key:

[localhost] % ssh -i /path/to/id user@remotehost

Connection to remotehost closed.

Better setup up ssh keys with empty passphrase than putting your password in a script.
