when installing 16.04 I must have checked an option that added a password at boot and at login. I don't really want to password at boot just the log in password. how do I disable it

From your description you opted for full disk encryption.

Unless you are a total Linux guru, you'll just have to re-install Ubuntu.

Even for a Linux guru it would be a pain in the neck.

UPDATE:

Here's a workaround from @Alcuin in the comments:

Just set your user account to auto-login. That way you still only have to enter one password at startup while keeping your disk fully encrypted.

If Ubuntu asks for an encryption passphrase during boot (i.e. on the text console before the login screen is displayed), this indicates that a full disk encryption method was used. (There's more than one way to do this, but I'll keep the answer general.) The encryption is handled by an extra software layer between the file system and the physical hard drive, not the file system itself.

There is no simple method or tool to undo this. With some knowledge about how Linux systems work, it can be done. You'd have to move the whole file system (or all files) to another partition (with enough free space) or external HDD. Then, remove the encrypted container, and recreate the file system without encryption. Finally, make sure that the new file system is properly recognized by the boot loader and mount -a before rebooting.

If possible, it's best to avoid this time consuming and error-prone procedure. Just do a fresh install. For a new users, this is the quickest and safest option.

The above quote was taken from here.
