I use Firefox as my browser and 1Password as my password manager. On my iPhone, I use 1Password + Firefox.
I look at https://passkeys.directory/ every so often and switch my logins from passwords to passkeys. This has included a lot of my common logins like GitHub, Google, and Microsoft.
There is a lot of confusing terminology. For some reason sites will say "login with Touch ID" or "login with Windows Hello" instead of "login with Passkey".
Aside from that quirk, I love it. 1Password syncs my passkeys between devices. I can use them both on my laptop and my phone. It would be inconvenient if I needed to login to a shared computer e.g. at a library or friend's house, but I don't do that often enough to care (though of course some people do, which is totally valid).
Sidetrack: the website mentions "driving espresso innovation forwards". Is this a thing? I love coffee but mostly just use a french press or a moka pot (which are more "great old school tech" than "innovation")
I will drink moka-pot coffee if that's all that's available, but espresso is what I want to have most days. So I have a good enough grinder and an mid-range espresso machine. It isn't always a success. Sometimes it's sour, sometimes bitter, sometimes too weak. Most of the time I don't have a clue why, so I can't address anything in particular, I can only try changing one of the few variables I can control with my setup, and hope to god that the other ones haven't changed on their own.
People are really serious about consistently producing real good espresso. Control and observability are what these machines offer.
If you want to fall into the rabbit hole Lance Hendrick's YouTube goes in depth into recent research and technique. And James Hoffman is a similar but more approachable source.
