alt Hacker NewsPassword managers for passkeys have a huge problem when dealing with any kind of remote support or working on someone else's hardware - you can't just copy/paste or type in the passkey so you're forced to install the password manager on a family member's/stranger's/employer's PC or do what? I'm not even sure. At least SSH keys have forwarding when you ssh to a remote machine, how do you "forward" a passkey?
With Apple's Passwords app, you can create "groups" for passwords and passkeys and share them with people. Once shared, the passkey/password automatically fills as if it was that person's own.
I have a "Family" group in my Passwords app where I share passwords and passkeys with family members for exactly this purpose.
