Q: how do i turn off keychain

Hello nugentpk,

Thanks for using Apple Support Communities.

If I understand your post correctly you want your Mac to automatically log in to your user account, rather than having to enter a password.  To get started, this is not Keychain, rather this is simply your login password.  Follow the steps in the link below to configure automatic login:

Set your Mac to automatically log in during startup

Have a good one.
