How to permanently associate an existing 1password login item with an iPhone app?

I have an existing 1password login item associated with a URL which works correctly for the web site. But when I launch the iPhone app the username/password are not filled in nor is 1Password popped up. (Note: iPhone auto fill is on and 1Password is the only password manager checked). When I press on the username field and click on "passwords", 1Password pops up with only "+Create item".  (I don't want to create a new login item as I already have one) There is no option to select an existing 1password login item. When I then search 1Password for the existing login item, my only option is to "Allow Once". which does correctly fill in the apps username/password, but the association to the 1Password login item DOES NOT PERSIST. The next time I launch the iPhone app, I have to search again 1Password to find it. Is there a way to force 1Password to persist an association with an existing login item with an iPhone app

Hi @seaubrey thanks for reaching out!

1Password integrates with iOS Password AutoFill in order to fill into apps on your iPhone. iOS is responsible for identifying fillable fields and for doing the actual filling, while 1Password provides the data that is to be filled. 

When you find that 1Password isn't able to suggest a login item for an app, this will usually be because the “website” field of the login item doesn’t match the app’s “associated domain”. The associated domain is the website address which is claimed by that app for autofill purposes and is passed to iOS Password AutoFill when you tap the "🔑 Passwords” button. Here’s what to try:

  1. Open the app in question.
  2. Tap the Password field, then the “🔑 Passwords” button on the keyboard.
  3. Check the Suggestions that appear in the pop-up. **If the “Passwords For” header also includes a website address**, that’s the associated domain, and you should make sure that the “website” field of the Login matches this. If you search for the matching login, you'll see Always Allow alongside the option to Allow Once. Choosing Always Allow will add the app's associated domain to a website field in your saved login item, so it will be suggested next time.

 

If the “Passwords For” header just says “Suggested Items” with no address, then the app developers haven’t set an associated domain, and you’ll have to search for it each time, because neither iOS nor 1Password will know what to suggest. That would be something that only the app developers can fix, as it’s part of how the app is written. In that case, I’d advise contacting them through the “App Support” link in their App Store listing to give them your feedback.

Let me know how you get on with the above and I'll be here to help if you have any questions.
