Okta / Lumos are the biggest offenders of this.

I suspect in that case it's to get their name in front of people's faces for marketing purposes. If things are actually seamless enough that you don't need to re-auth, you won't be reminded that their company exists.

Why in the world does it need you to type a code id you have already accepted it at the other device? This whole flow is stupid, I guess they want to cover their asses.

I agree with you, but it's the same reason why Microsoft asks you to type a numeric code generated by their Outlook app in order to login. It's to prevent people from dismissing the alert by clicking "OK" without even reading (especially if they're in the middle of something else, e.g. during a scam phone call).

Right, the numeric code is proof of intent. In theory, tapping "ok" or "yes, this is me" should be proof of intent. In reality, it's common for those who have compromised someone's password to flood people with these notifications and auth prompts to get them to eventually say "ok," even if by accident.

Same behavior here. I use TouchID to log in several times per day, and am required to enter a password "to enable TouchID" about once per week. iOS and macOS both. This feels reasonable to me.

It's annoying to ever have to enter a password manually, but it does make sense every 1 or 2 weeks to force it. Not even as a security thing but as a memory thing. It's incredible how something that you seem to know so well can get flushed from your memory after you stop recalling that knowledge regularly.

Exactly. I have enabled TouchID for a couple of banking apps, and I am dreading the likely need for the password reset dance when the time comes (it's been years).

I use a password manager, but I've always kept the actually important passwords in wet memory only. When I used the web interface regularly, that was not a problem. However... :-/

Wouldn't frequent reauth be beneficial for stolen sessions?

E.g. If you set your session timeouts to a ~1 day then by the time your session cookies are up for sale on the dark web, they will be expired.

The article doesn't mention this and it's the main reason I advocate for auth sessions that are as short as practical.

A client of mine has a 30 min timeout on basically all their systems. I hate using Jira as it is, but having to login pretty much every time I need to go look at my tickets just makes it awful. And then I end up on Hacker News instead of doing actual work.

Few things worse than spending 30 minutes writing something only to be asked to login when you submit it. Fortunately these days most services will cache your work.

Though to rely on Jira to respect your work or your browser functionality is madness.

I have really strong opinions against the device-secured biometric stuff. On my own devices, I will never use it as it dramatically lowers my security posture.

Further, the development of this ecosystem is to the exclusion of alternative OSes. Windows Hello and whatever apple wants to call their suite of biometric goo is elevating them to a place in my life that is unacceptable by virtue of the unwarranted trust granted to them.

If your session cookies were stolen, they can be stolen again and again too? Timeouts of 1 day assumes the cookies can only be stolen once.

Remember when it was called SINGLE sign on? Emphasis on SINGLE? I mean, this whole idea has been such a mess forever. Why am I prompted to SSO hundreds of times a day?

As far as I've understood/remember SSO was logging on with a single ID and not logging on a single time.

Zero trust states that you don’t implicitly trust an entity even if they were previously authenticated. So is this a critique of zero trust? More productive might be to say that we shouldn’t blindly force reauth if our risk profile doesn’t warrant it - just like any security mechanism.
