Designing fast sign in forms – diving into the data

We put a hidden field on the page to accept a password from a password manager. If the password manager fills it, we expose the field to indicate the password was received.

---

The second page is helpful for users who originally sign up with Facebook/Google, and therefore don't have a password to enter on the first page. (It's also helpful for SAML, but we don't support SAML quite yet.)

Edit to add: Even if we had email/password on one page for everyone, I would still expect Social Sign In to win.

We don't actually have telemetry on password manager vs keyed, but the way things are distributed we can make an educated guess. I'd guess that PW manager users have a chance at beating Social Sign In users, but too many are still keying their passwords for passwords to win overall.

Thanks for another blog idea :)!
