There's a good blog post from @april.social about cookie parsing: grayduck.mn/2024/11/21/h...

I set up this account, then nerdsniped myself right past the process of crafting a witty and enticing "Hello, world!" post to instead spend a few minutes trying to figure out whether Bluesky supported security keys rather than email for 2FA.
