For every platform/ecosystem you are using (Chrome, Apple iCloud), you had to create a new passkey. For people using multiple different devices and platforms, this is a headache. I want to sign up once and be done with it.
Definitely! My understanding is that this is where passkey/password managers enter the picture.
My preferred password manager is 1Password, so once it gets passkey support I imagine I'll use that for everything. Until then, I'm depending on the limited sync functionality in iOS/macOS and Chrome.
Agreed. If mobile operating systems allow password managers to support Passkeys, and password managers implement the functionality, then I will absolutely switch.
