This makes sense given how often they'd fail. When I log in it takes me one attempt. When someone is using stolen credentials they might have to make hundreds of attempts before actually logging in.

That, and most websites remember your computers forever so you rarely ever need to log back in.

I wish. If that were the case, there would be almost zero market for 1Password, Keychain, and a dozen other solutions.

I don't buy these numbers at all. 90% seems stupid high for retail. From the report, "[...] we rely on data from the Shape Network. Across the US, Shape’s customers represent: [..] 40% of Mobile Retail (by in-store payments)." "We estimated the number of credential stuffing attacks using the total number of credential stuffing attacks observed on Shape’s US customers and the total proportion of the US industry our cu…

Why would you think 90% is high? That's only 9 in 10. Remember, attackers using dictionary attacks are going to be trying hundreds or thousands of log in attempts, and a real user is only going to try at most a handful of times.

You don't need that many attackers to easily approach 99% or higher. I'd say 90% is likely conservative for some companies.

I recently joined a website the did away with passwords, the only way to login was to enter your email address and confirm by pressing a link in the email, while this adds a pain point for customers it offloads most security implications onto the email provider.

Unfortunately, that doesn't imply that the site is secure either. An attacker could also try to brute force the link, though it's likely more secure than most passwords at least. But if the link is not expired, the attacker could still eventually get in.

How does that deal with email providers that follow all links with their virus scanner? (many corp emails...)

Usually these credentials are one-time usage.

The only thing that implies security is an airgapped (even that is debatable) or powered off computer.

"Click to continue" Javascript on the landing page, IME. Or a time-based limit, which seems more user-friendly: if you close the tab you can reopen it or go back to your email.

I'd guess however any service that requires account confirmation to work.

This sounds like a solved problem, though I don't really know.

I think 90% is high for a few reasons:

1) Rate limiting of login attempts takes a bite out of the large numbers you're talking about. If we are only looking at retail companies without rate limiting, well, duh, I guess >90% makes sense, but I expect a large portion of the global e-commerce retail segment _does_ employ rate limiting of logins.

2) The report lists, "Averages derived from customers’ login traffic before Shape Enterprise Defense was deployed on login applications" - so this is absolutely a biased sample. These are clients that signed up for help stopping this problem.

3) It bugs me how ambiguous the report is about how they aggregate to 90%. I worry it's a simple [total fraudulent logins] / [total login attempts] across all their client retailers, which will be heavily biased by the retailers that don't have login limiting, and doesn't really describe the situation. A much better number I'd like is the median percentage of fraudulent logins attempts across retailers.

Passwords can already universally be recovered through email. I wish ALL sites had this feature. It's essentially a one time password, that expires.

Yeah, but be careful never to use an email that you might lose access to (which in principle, could be any email).
