Definitely a nerdy, but also understandable, piece from Ricky Mondelo ("software engineer, known for my work on passkeys, password management, and other app/website authentication technologies") on the use of magic links and passkeys:

You’ve almost certainly encountered magic links in your time online. A “magic link” is just the special, one-time link you get emailed to you that will sign you into a website after giving it your email address.

If you're interested in #security #authentication, or just general #privacy, give it a read.

My favorite bit though was this:

acknowledging that most people have on average approximately 0.8 correct passwords in their memory at a time

I use a password manager so that in general, all my passwords are long and randomized. But even then, when I only need to remember one strong password, remembering what I recently changed it to, or if it's a variation, validates the humorous "0.8 correct passwords" comment.
