Big Tech companies want to chain your passkey to their products. Enter Proton Pass, which allows you to manage and use passkeys across all devices seamlessly.
Not only passkey managers but websites too. I tried to set up a passkey for PayPal but they don't let you set it up unless you're using chrome or safari
This seems to be about android, meant just desktop, where I use Firefox and bitwarden. It works fine with GitHub where I created and use a passkey but PayPal's faq says they only support chrome and safari.
This is one of the major problems with passkeys that passwords don't have. Are they device-specific, browser-specific, browser-on-device specific? Can I use the same one or do I need a different one if I'm on chrome but two different desktops, or desktop and laptop or if I use both Firefox and Chrome on the same phone/laptop? Until this stuff gets worked out, passkey aren't going to go mainstream.
In theory, as the article mentions, you should be able to save them to your password manager of choice (if it supports passkeys, bitwarden does on the browser extension but not in the android app yet) and they will sync up through the cloud. So you might have just one passkey for GitHub for example and use that same one on all your devices to log into GitHub.
