Normally we verify email addresses by sending users an email, making them open their inbox, find the email, and click a link to return. Friction at every step. What if it could be this easy?

Chrome 144 introduces a new `<geolocation>`HTML Element to implement more impactful user location permission request flows. The new element serves multiple purposes, from location sensor access request as well as providing access to location data without the need to call the Geolocation JS API.

Signal API is now available on Chrome for Android. A user deletes their credential on the website, but the passkey remains in their passkey provider. The next time they try to sign in, the passkey provider offers a passkey that no longer works. A sign-in attempt will fail and this isn't ideal.

BFCache can hugely influence your page performance for URLs high on Back Forward Navigation types. If you use CrUX or RUM and you see a lot of traffic in % attributed on Back Forward and few on BFCache maybe you are leaving money on the table! CruXVis can help you measuring this opportunity!

Bonus: RayBan also unlocked BFCache and measure the impact of Prerender by using CrUX Navigation Types. Take a look at the data by using cruxvis.withgoogle.com, if you see a high % of Back Forward Navigations and few that are bfcache perhaps you should focus some effort to unlock that potential!
