1Password's Passkey support feels very aggressively growth-hacky to me. They intercept calls to `window.credentials` and if you want to use 1Password along side other verifiers like Yubikey, you need to go into your settings and disable their passkeys offering entirely. It's similar to how they also intercept (and globally disable!) Google One Tap prompts in order to show their own OAuth prompt. I only use their Chrome extension so I'm not sure if the native app experience is significantly different.
