> Now, you have one more option—and it’s already in your pocket. Starting today in beta, your phone can be your security key—it’s built into devices running Android 7.0+.
You know, it's nice they phrase this as an "option", but in my experience Google has the habit of forcing me to have my phone on me when I login from a new location / new device, something I never asked for and apparently cannot disable.[0] This has locked me out of my Google account more than once which also locks me out of anything that sends 2FA to my Gmail or Gvoice. I guess I'm thankful that I've learned this in non-emergency scenarios, as I'm now prepping to degoogleify myself, but it's a user-hostile in my opinion. Security always has convenience trade-offs, but let the user decide where they want to draw that line.
