Are you who you claim to be?
User logins protect websites from malicious actors, like spammers and trolls. So when you go online, only people with legitimate credentials can access the useful features of the site -- and others can't impersonate you. For years, you've used logins -- such as a username and password -- to prove to the site that you are who you claim to be, like this:
Some go even further and add a second factor to authenticate with, like an SMS code or one-time-password generator like you might have in the Google Authenticator app.
But, we figured it would be easier to just directly ask our users who they are -- so, we did! Following on our earlier success with No CAPTCHA reCAPTCHA, we’ve begun rolling out a new API that radically simplifies the login experience. We’re calling it "Credential-Free Authentication" and this is how it looks:
A brief history of user authentication
While the new login API may sound simple, there is a high degree of sophistication behind that modest interface. Authentication has long relied on attackers not having critical secrets, like a password or random number generator seed or other private information. You may have heard the traditional formulation, that authentication requires you to provide something you have, something you are, or something you know.
However, our research recently showed that it's about as likely for the genuine user to be missing the credentials as it is for a malicious actor. How many times have you forgotten your password or encountered a bug with your password manager? (Not GPM, of course!) Thus, challenging users for credentials is no longer a dependable test.
Furthermore, attackers are often able to steal user credentials, forcing providers to rely on a secondary layer of fraud identification, so as to lock accounts when users behave suspiciously. You've seen this if you've ever had a credit card declined for an unusually large or remote purchase.
Introducing Credential-Free Auhentication
That got our security engineers thinking: if we already have to analyze a user's behavior in order to catch account compromises, why not just use that as the authentication? It would cut two carrots with one knife! After all, an attacker might be able to guess your password or your credit card information, but they will never be able to mimic the full depth and breadth of how you interact with websites, from your browing history, to your cookies set, to the way you move your mouse.
Following the "No CAPTCHA" model above, we developed an Advanced User Analysis backend for logins that actively considers a user’s entire engagement with the the Internet to determine who that user is. This enables us to rely less on "Do you have the secret?" and, in turn, offer a better experience for users. Now, users can just click a radio button, and in most cases, they’re logged in. In fact, you'll rarely have to log in at all, because sites will "recognize" you, just like you don't have to show your ID to go into an event venue a second time if the bouncer recognizes you.
But are you really that person?
However, authentication challenges aren't going away just yet. In cases where our tracking cookies and other behavioral metrics can't confidently predict who someone is, we will prompt the user for additional information, increasing the number of security checkpoints to confirm who the user really is. For example, you might need to turn on your webcam or upload your operating system's recent logs to give a fuller picture.
Adopting the new API on your site
As more websites adopt the new API, more people will see Credential-Free Authentication. Early adopters, like Snapchat, WordPress, Twitch, and several others are already seeing great results with this new API. For example, in the last week, the number of support tickets for account resets on WordPress went down by 90%. Twitch reported similar figures -- and also was able to unmask several sockpuppets who had been manipulating discussions and vote totals.

Good users, we'll continue to keep the internet safe and easy to use. Bad users, it'll only get harder to hide yourselves and take over legitimate accounts -- sorry we're (still) not sorry.
Edit: Yes, this was an April Fools joke.
