How does 1password find a password for a specific application? How to bind a login to a specific app

I am trying to use 1password on iOS to log in into an app developed by, it's probably a fairly small app:
Most of the time when I use some app 1password is smart enough to find a relevant password to autofill. However it doesn't work for this specific app.
I know on Android 1password creates a special field with the app id (, however iOS seems to work differently.


  • Is there a way to make bright energy app (or potentially other apps) use a specific login entry from 1password?
  • What mechanism is used to match a login and an app in 1password on iOS?

1Password Version: 7.7
Extension Version: Not Provided
OS Version: iOS 14.0
Sync Type:

    Hi @legeana

    Thanks for taking the time to write in. I'd be happy to help with that.

    I know on Android 1password creates a special field with the app id (, however iOS seems to work differently.

    The concept is similar, but with autofill on iOS the onus to handle this properly is on the app you want to fill into, rather than on autofill. In order to have the appropriate item suggested the app in question must define an Associated Domain as part of their metadata that they submit to Apple. This Associated Domain would have to match the URL in the website field on your item for them. For example, the Facebook app has an Associated Domain of such that any Login items you have that have that URL listed as a website will be matched. If the app doesn't specify an Associated Domain at all, then it isn't possible to autofill to suggest a match, and will instead show all possible results. That's exactly the case here. The 'bright' app doesn't have an Associated Domain. This would need to be added by the app developer in order to be more compatible with autofill.

    Apple has developer documentation available on this, here:

    Supporting Associated Domains | Apple Developer Documentation

    I hope that helps. Should you have any other questions or concerns, please feel free to ask.
