Yubikey will never prevent your data from being leaked. They didn’t crack your password.

But a random, unique password prevents further harm. They can’t get data from another site just because they hacked this one.

Have random, unique passwords. Use a password manager. Done.

Still vulnerable to phishing, and that's where Yubikey & U2F can help.

That depends on how your data is being leaked. Of course it does not stop the service provider from leaking your data (intentionally or unintentionally). It protects you from phishing attacks.

Sure. These are still good practices even with a yubikey.
