I had to mess with this just yesterday.

I got a new cell phone and installed Microsoft Swiftkey and tried to login to Microsoft. It said my device's password or security manager would popup, but it never did and it never showed an option to login via password, just a mostly blank screen. I tried logging in from my laptop browser and it immediately tried using a passkey, but I've never created a passkey for Microsoft, so it errored out, still never showing an option for password login. I tried again and it errored out again and FINALLY showed the option to login via password. It had to fail 2 times to finally show the option for password login.

I was finally able to login via password, then had to go to Microsoft's passkey management page to create a new passkey, store it in 1password, and use that on my phone.

I'm a software engineer and it was annoying and time consuming and took a minute to figure out. How are non engineers supposed to even use this crap?

It's gotten to the point where I assume "product manager" is a synonym for "incompetent person who breaks working products."
