That assumes the device/app I’m logging into supports that. It also assumes I have my password manager on a device that can scan QR codes.
Are passkeys ubiquitous? It doesn’t feel that way. Tech demos are nice, but they’re just tech demos. When I’m doing my taxes I don’t want to find out I can’t download my data in TurboTax because I can’t login to my bank with a passkey via their app. Or maybe I want to use some old hardware, where the apps haven’t been updated with QR codes and passkeys, I guess I’m out of luck.
Too many edge cases. They are trying to sell passkeys as a magic way to login. I’m not going to entrust my ability to login to magic.
Also, scanning QR codes to authenticate feels very janky. Isn’t that why CurrentC failed? No one wanted to do a QR code dance with their phone.
After entering your username, you select an option to use your other device to sign in and scan a QR code with it.
