The "login" keychain is encry..... (the rest of your sentence).
You can have many more keychains, and they can have far more sophisticated passphrases. I have an "Internet Identities" keychain (for iCloud, Gmail, Dropbox, VPSs, Github, ...) that has a very long passphrase and is not unlocked at the login, nor it stays open after you enter the password (so, if Safari asks for the password and I enter it, the keychain doesn't just stay "open" for all apps to feast upon).
* appleid.apple.com
* daw.apple.com
* id.apple.com
* secure1.store.apple.com
* secure2.store.apple.com
If they have trouble getting something as simple as that right, I'd like them to stay away from my keychain.
It's unknown how many of those bits the NSA knows already.
