How to download Chrome extension which would work with a standalone 1Password 7 with a lifetime license?
I have converted the old standalone extension that works with non-cloud and non-subscription 1Password v7, so that now it uses Manivest v3 and works in Chrome. The link below allows you to see the diff in files between V2 and V3 and load the extension unpacked in the developer mode of Chrome Extensions Manager. Here's the link: https://github.com/MartinMiles/1password-Chrome-Extension-manifest-v3 Now it works again in the latest updated Chrome for me, and works like a charm! Ask: if that solves your problem, please give it a star so that I know it actually helps real people. More on reddit.com

Is it more secure to *not* use the Chrome extension?
Personally, I’d avoid Chrome altogether. If you like Chrome, then go ahead and install the plugin. You’ll be fine. More on reddit.com

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If I choose to continue using "outdated" software and OS, that's my choice, but at the very least, I should be able to access the tools I paid for.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!

8 Best Password Managers (2025), Tested and Reviewed | WIRED
October 30, 2025 - Rather than copying and pasting passwords from your password manager to other apps (which puts your password on the clipboard, at least for a moment), 1Password is integrated with many apps and can autofill. This is more noticeable on iOS, where inter-app communication is more restricted. After signing up, download the app for Windows, macOS, Android, iOS, Chrome OS, or Linux. There are also browser extensions for Firefox, Chrome, Brave, and Edge.\
