FWIW: I find passkeys to be a very simple and easy to use concept.
Simple: it's like a password that I don't have to type in
Easy to use: because I use 1Password and just have it installed on everything. On Android, it can be set as the default passkey provider so, even on mobile, I am using passkeys shared across devices.
Is this "less secure" because I'm sharing the keys through 1Password. I suppose, at some level. But before that, I was simply sharing passwords through 1Password in the exact same way. So, I don't think my security posture has changed any.
What has changed is the UX and IMO for the better. Now I don't have to generate/fill/copy-paste text strings for user names or passwords. 1Password knows what site I'm on and usually responds automatically when I'm in a passkey context. If I have more than one passkey available, because I have multiple accounts (for something like Google Workspace), it shows me options and I pick the one I want.
Honestly, it's mostly a "just works" system and I like it a lot better than passwords.
YMMV, of course.
My problem with passkeys is that "don't have to" is actually "don't have to, and couldn't if I wanted to".
This is a big problem I have with "just works". Everyone is used to services only allowing a single password. I know the answer to this, but it's not clear in the marketing or how it's explained to normie end-users: Won't creating a passkey erase my password? How do you sign in on another device? Won't that change the passkey and lock me out from the first device?
I try to use passkeys when possible as I'm also a 1Password user, but this hardly "just works". Firefox on Windows often triggers the Windows password manager for passkeys (some how this is only on some sites), making it impossible to use 1Password.
I've seen the same on Android too, and I think there's a difference in how Chrome and Firefox are handling the requests.
Then you get in to cases like a Microsoft Account. You need to use your account to log in to the device that has the passkeys, so the workflow never works properly and you have to fall back to another method.
Amazon is another one. If an app like Libby redirects to Amazon, I get a different, passkey-less password prompt, so I need to have a password readily available.
It's great when it works, but honestly 1password with straight up username/passwords is probably just a better UX in the end.
Everything you said is _also_ true if you use a password manager than can interact with the browser (which you're already doing).
Plus, that doesn't have the negatives/limitations of passkeys.
This. Honestly, most of the arguments I read against passkeys just sound like “old man yells at cloud.”
It’s not that difficult. Spend 10 minutes researching the topic and you’re fine. Passkeys are so much more convenient than having to use passwords. When implemented right, it’s literally one click from opening the login page to being signed in. On all of my devices.
OK now say you're on a work/library/friend's computer and you want to look up an account in 1password on your phone so you can type in the password. Passkeys don't support this very basic and common workflow. Meanwhile there's no real security benefit over password manager generated complex and not reused passwords.
