1Password requires me to install a browser plugin?
The extension is an essential part of the product, if you are using 1Password without the need for saving and filling logins in browser, I would greatly appreciate hearing more of your use case to understand how you are currently using 1Password. More on reddit.com

Why is 1Password Chrome extension so in-consistent with the 1Password MacOS App

Hey, u/mailboxdavidb. Broadly the apps have more of a focus on the managing of your library of items and the extensions, mini and Quick Access offer a more compact interface focussed on filling via suggestions or searching. If you let us know more about how you would like to see tags work within the extension we can absolutely get this raised with the team though.

And if you'd like to send us more information on a private channel if f you send an email to [email protected] with a link to your post in your message we'll have a member of the team reach out.

As for the ordering, thanks for the heads up and we've already got this fixed in 1Password 8. 👍

r/1Password on Reddit: Where can I download the 1Password Classic Extension for Chrome.-
October 1, 2024 -

I purchased a "Perpetual" license for 1Password 7 just one week before they announced the switch to a subscription-based model. To me, it's frustrating and feels like an unfair business practice. Why sell a perpetual license and then make it nearly impossible for your customers to get the extension for supported browsers and operating systems?

If I choose to continue using "outdated" software and OS, that's my choice, but at the very least, I should be able to access the tools I paid for. I also strongly resist buying into subscription-based software and entering what I see as the "Subscription Exploitation Economy."

I've tried downloading the extension "1Password-4.7.5.90.crx" from multiple sources, only to be hit with the infamous "Error 400." I even found official posts from 1Password staff linking to the file, but the same error persists.

Does anyone know where I can download the classic extension that works for 1Password 7? Any help would be greatly appreciated!

November 8, 2024 - If there is a use-case I've not heard before I want to hear about it and learn more! We've already been discussing this internally because using 1Password without a browser extension goes against all of our ux research findings where the experience is preferred and yes, using the extension is more secure.

Browser extension vs App | 1Password Community
April 24, 2025 - Strictly speaking you don't need both the 1Password desktop app, and the 1Password browser extension, but I prefer the experience with both. If you were going to pick only one, I would recommend the 1Password extension so you can easily fill and save credentials while you browse.
