I don’t know how useful/popular some of these sites are (I’d never heard of carnival) but until there’s a few dozen major sites with support, they could all be listed.Are these solid enough to add to the wiki post at the top of this thread?
Nice, that’s another one. Their website doesn’t support passkeys yet but the app does for sure. You can create multiple passkeys but can’t delete your password or surplus passkeys.The CardPointers app is the first passkey-supported app I’ve seen in the wild that is not locked behind some 2FA barrier as a ”security key” like Google and Microsoft. I tried setting up a passkey in Microsoft Authenticator but it wouldn’t let me because it thinks I’m on a private browser. I tried on the website but the option doesn’t exist, so I left a one-star review on the App Store to get their $h!t fixed
The Kayak app as well as their website supports passkeys. The app has the benefit of not needing to type your email, it automatically prompts to use an existing passkey.
