We have a full list from all developers who have informed us they have integrated here: https://blog.agilebits.com/1password-apps/ There are likely other apps that are not on this list, but if they don't tell us they have added support it's difficult for us to add them. You can request your favorite app add support, often times it only takes a developer 15 minutes or so to add it. Details in our github repo here: https://github.com/agilebits/onepassword-app-extension Let me know if you have any questions! I handle all of our app extension customer support and code maintenance.

The only iOS app I can recall that integrates with 1Password is HipChat. Integration requires using AgileBits' extension (https://github.com/AgileBits/onepassword-app-extension). The password manager doesn't have any OS-level hooks that allow it to work with any app.

1Password only works in non-Safari browsers if those apps include a less optimal SDK that provides a generic password filling conduit. It is not something that WKWebView automagically does. See https://github.com/AgileBits/onepassword-app-extension
