Fill not working

Babbling I deleted the other screenshot with your email address. Let me know if that works. As a note, you should be able to edit and delete the screenshots from your posts too.

As for the id.tinypass.com URL (and auth.piano.io website), I'm very sorry for the confusion. Some websites are connected to each other through the login process on the backend. This could be done because the company that owns the website has other websites. They may want to handle the login process for all their websites in just one place. They may also use a third-party service to handle their login process. If the third party service requires for their own URL to be present in order for logins to be autofilled, then 1Password would accommodate that, as seen here.

It looks like christianitytoday.com uses the TinyPass service for https://piano.io/product/id/. The id.tinypass.com URL was added by 1Password in order to make the filling process as smooth as possible. We use a list of associated websites and interchangeable domains from Apple (which is https://github.com/apple/password-manager-resources/blob/main/quirks/websites-with-shared-credential-backends.json) as well as a list we've gathered ourselves in order to do this. An example of this is the domains apple.com and icloud.com. When you create a login for apple.com, 1Password automatically adds icloud.com to it.

I would not be concerned about the id.tinypass.com URL or the auth.piano.io website (where the TinyPass URL re-directs). In fact, I recommend adding id.tinypass.com back to your Christianity Today login so that filling will work. You can do that by editing the login through the app. You can also save a new version of the login from the website and delete the old login.

Again, I'm sorry for the confusion. I do hope I've been able to clarify the situation. Let me know if you have any other questions!
