There’s a survival game called Grounded that’s basically this but even smaller. And a coop story action/adventure called It Takes Two that does the same.

I wrote a whole thing on this, but tldr; I switched from Gmail to iCloud about a year ago. Gmail is better at filters, search, web UI, and spam filtering. iCloud is better at native UI, offline support, and ecosystem integration.

Overall I’m happy with it but only because I’m willing to pay the costs for the benefits, which I think is pretty rare.

It depends on your password manager and sync method. With most if I take all your devices away from you, you can’t go to any public computer and access all your passwords using only what you know. You need to have one of your physical devices.

Password managers do have two factors: the vault (have) and the master password (know).

Thinner the better. It creates more places for air. Same for curly fries. Even a slightly bent normal fry hogs more space than a straight one.
