Earlier quoted context omitted.
I agree with this point. I retype my user information, even while logged in, at least a few times a week.
That's odd because I never do. I'm using two-factor and I only have to retype login information when that expires (approximately 30 days I believe.) Also, someone did phish my Google cookies and Google immediately shutdown my account and made me type in something from a text to reactivate my account. Overall I'm pretty happy with both of those circumstances.
Some of the accounts don't work in every context, i.e. the pre-Google YouTube account doesn't seem to work for displaying public Google docs embedded PDFs. Sadly the accounts can be linked but not merged[1] which means I'm stuck.
