That's not true, though. You would still have to either press tab (now enter), or click the second field to enter the password.

It's very true. The click isn't the problem, the "waiting for transition between pages" is the problem.

Type username/password = ~1s each

Single keypress = ~0.1s each

Page load = ~2s

Before: username + tab + password + enter = 1 + 0.1 + 1 + 0.1 + 2 = ~2.2s

After: username + enter + page load + password + enter = 1 + 0.1 + 2 + 1 + 0.1 + 2 = ~4.2s

Roughly doubling the amount of time it takes to enter your information is significant and annoying.

Except it doesn't even take a second for the password input to appear. Where are you getting those numbers from anyway? When I tried it, it only took about 152 ms for all the data to load after submitting the e-mail address.

It depends greatly on your location, connection and browser. Many users are stuck on low quality internet connections or mobile devices where things can easily take a full second or more.
