The feature even supports an inline generator and account creation wizard for when you’re signing up for new services, which in my experience is one of the biggest barriers to getting new users to understand and use 1Password: they don’t add new accounts they sign up for into their vault. In addition to the same handy integration for filling 2FA codes and their helpful password generator for new sites, X adds a built-in form filling utility, similar to the “autofill” capability that browsers have had for a long time, but with access to your 1Password account if you’ve got it unlocked. The full features of the 1Password desktop app are available from within the extension - access to multiple vaults and all your accounts, editing and organizing your accounts, and creating new ones.

One of their big motivations here was deepening the cross-platform support since you can install Chrome (and Firefox) on so many OS platforms, including Linux.

I don’t know much about the tech backend or advantages of building a Chrome extension versus a “thick-client” browser plugin, but it seems like it’s certainly a benefit to conform to the browser’s best practice for building add-ons and extensions are the way to go in Chrome. Since access to accounts is most useful in a web browser context, implementing it as an extension makes sense. But recently I set up the 1Password X browser extension they first released a couple of years ago, and I’m converted. For a long time I’ve used the full 1Password desktop app and its browser plugin that installs alongside for support inside of Chrome.
