Open and fill uses email when no username or password

It sounds like it might be specific to the way this website is structured.

This seemed most likely. One detail which may be relevant is that I created the Login item before I had a username or password.

Additionally, if it's being replaced soon, it may resolve itself,

That was my hope.

but the info below will still help us understand what's happening:

• Which operating system, browser, and 1Password version are you using?

Multiple up-to-date operating systems including Ubuntu 24.04 Desktop and Fedora 44 Workstation, latest Google Chrome with up-to-date 1Password Beta extension from the Google Play store, 1password package from the 1Password repo for each platform.

• Does the same thing happen if you fill on this page using other methods, such as the inline menu or a keyboard shortcut?

Yes, but with an interesting quirk. Both the Sign in pill overlay at the top of the window and the Open icon drop-down in the input field show the username, but once selected, fill the input field with another field from the Login item.

• Is the email address that’s being filled your default email address set in your profile, or an email address from an existing Identity item?

When the input field was filled with an address, it was the email field from the Login item for the site. Now it’s filled with the value of a custom field.

The only way to fill the input field with the value of the username field is to copy and paste it.

Looking at the JSON for this Login item, the source of the problem seems obvious:

    "fields": [
      {
        "value": "[The correct password]",
        "id": "",
        "name": "password",
        "type": "P",
        "designation": "password"
      },
      {
        "value": "[The correct username]",
        "id": "M_layout_content_PCDZ_M67QS82_ctl00_txtLoginName",
        "name": "M$layout$content$PCDZ$M67QS82$ctl00$txtLoginName",
        "type": "T",
        "designation": "username"
      },
      {
        "value": "[An account number]",
        "id": "M_layout_content_PCDZ_M67QS82_ctl00_validationControl_fldAccountNumber",
        "name": "M$layout$content$PCDZ$M67QS82$ctl00$validationControl$fldAccountNumber",
        "type": "T",
        "designation": "username"
      },
      {
        "value": "[An account number with a missing digit]",
        "id": "M_layout_content_PCDZ_M67QS82_ctl00_validationControl_fldAccountNumber",
        "name": "M$layout$content$PCDZ$M67QS82$ctl00$validationControl$fldAccountNumber",
        "type": "T",
        "designation": "username"
      },
      {
        "value": "[Another account number]",
        "id": "M_layout_content_PCDZ_M67QS82_ctl00_validationControl_fldAccountNumber",
        "name": "M$layout$content$PCDZ$M67QS82$ctl00$validationControl$fldAccountNumber",
        "type": "T",
        "designation": "username"
      }
    ],

The input field is filled with the last entry, which I obfuscated as [Another account number].

The entry which I obfuscated as [An account number with a missing digit] does not even appear in the Login item.

Unless you suggest otherwise, I plan to replace this Login item with a new one initiated by a first login to the site, even though that may leave the question of this broken Login item’s creation prior to the username and password for another occasion.
