This is sensational OSS, mad jelly of the people working at 1password.
I see how passkeys can be beneficial for 1password as people could just login to anything with their 1password master password and not store or reach out for their phone every 30s.
I wish them well. I wonder if it's time already to ship websites with just passkeys support instead of user/pw, social login, passkeys.
It has the potential to simplify authentication a lot while making it safer.
