RE: Logging in to your Intuit account and verifying your identity helps you protect your data and your account. 

How?  How can logging into my Intuit account protect my Intuit account? Seems like circular logic to me...

RE: This is to make sure that you, and only you, can access your account. 

Yes, that's what the password on the intuit account does, but how does logging into my account make sure that only I can access my account? The password does that, not the act of logging in, right?

RE: Also, QuickBooks is accounting software, it's necessary to have the credentials like the user and the password in compliance with the law. 

I expect that is up to the user, not Intuit. I can't imagine the US government stating that software manufactures must require a password to open a file. Many don't, in fact, which supports my claim. In any case, the complaint isn't about requiring a password to open the file. It's about requiring both a password and logging into a remote account on Intuit's servers. I'm very sure the government does not require any such thing.
