I LOVE passkeys. That said, I store them in my password manager, which means anywhere I have access to my password manager, I can easily login via passkey. I can understand they would be a pain if I was often using new devices and did not have a password manager. I also admit it can increase the risk of lockout, but the sites I have passkeys for generally have recovery methods.

The only issue I've had is sometimes a website has poor support for my password manager, and I can't find a way to put in my passkey. That is very annoying. The benefits are worth that IMO - can't forget my passkey, can't phish my passkey, can't be hacked serverside. It's a clear upgrade to passwords

I feel if the _website_ needs to have support for your _password manager_, then that technology is way too fragile for me to want to use it.
