wired.com Luke Larsen 2026-01-30 17:30:00

You could certainly make the argument that cheap Chromebooks keep the world running. That's at least true in schools. But for all their importance, not as many new affordable Chromebooks come out each year as you might think. Asus is changing that in 2025 with the Chromebook CX14, a surprisingly pleasant 14-inch laptop that costs just $429 in its higher-end configuration. As far as cheap Chromebooks go, this is among the best. Blending In Photograph: Luke Larsen The CX14 might not look like

How to sync passkeys in Chrome across your Android, iPhone, Mac, or PC (and why you should)

Lance Whitney / Elyse Betters Picaro / ZDNET Passkeys promise to replace passwords as a more secure and convenient login method. But they still have a way to go before fulfilling that promise. That's because passkeys are often way too difficult to set up on one device, let alone all the devices you use. The industry itself offers no standard or consistent method to save and store passkeys, so each company has cobbled together its own process, which may or may not work. Also: Passkeys won't be
