Question

Open and fill uses email when no username or password

When a Login item website is selected with Open and fill, despite no username or password, the 1Password extension opens the page and fills the username with the email field and submits.

I have tested this once on one out of one web site which does not offer or suggest logging in with an email address.

Is this intended or desired behaviour?

I did not want or expect this. I expected the web page to open and the username and password fields to be filled with the values specified in the Login item, i.e. left blank. With these fields blank, I did not expect the form submission.

But it got worse…

After a username and password were added to this Login item, autofill decided to fill the user name field on the web site login page with a custom text value from the item, completely ignoring the username.

Again, this is a case of testing once on one out of one financial service web site which I’m not mentioning and which is about to be replaced in a few days. Nevertheless, this looks like terrible behaviour by the extension.

Hi ​@AJCxZ0, thanks for reporting this. I’ve done some testing on other websites, but so far I’ve not been able to reproduce the behaviours you’ve described. For me, using Open and fill with an item with blank username and password fields opens the page and doesn’t fill anything into the fields.

It sounds like it might be specific to the way this website is structured. I understand that you’d prefer not to share what website this is. Additionally, if it's being replaced soon, it may resolve itself, but the info below will still help us understand what's happening:

  • Which operating system, browser, and 1Password version are you using?
  • Does the same thing happen if you fill on this page using other methods, such as the inline menu or a keyboard shortcut?
  • 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?

Looking forward to hearing from you!
