how to enter url so it will fill passwords for apps

I think it has happened for a few, but the one I remember most recently is Tavour. If I find others, I will add them to the list as well.

I am using the auto-fill feature. When I get to a login screen, I see the Passwords section at the top of the keyboard. I tap it, and it opens 1Password, but then I have to search for which login item to use to populate the fields, instead of it suggesting that I use a specific login item. I am pretty sure I have seen this work before, but I don't know the specific app. Also, there was some way I entered the url for a login item as an additional url that seemed to make this work, but that is what I can't remember. I have many hundreds of login items, so I can't really open each one individually, but I don't know of a way to search for it either, so I couldn't find this out on my own.

I did test this out on another app (AAA), and when I logged out and then back in, it has a separate username and password screen. When tapping in the username field, I was not presented with the Passwords section at the top of the keyboard (I am assuming b/c it is not a password field, which is fine), but after I entered that, when I tapped into the password field on the next screen, I was shown the Passwords section, and when I clicked that, it opened 1Password, and the only item in the list was AAA. Compare this to when I do the same when logging into the Tavour app (and others), I get a list of ALL my login items, and then have to search for what login I am looking for. I hope this helps you understand a little more. If you need more info, please let me know.
