1Password Sometimes Double-Fills Password Field

Hey @nickfromdc, does this issue happen consistently on specific websites or does it happen randomly? By double-fill, do you mean that 1Password fills in the password twice in one field? Or does 1Password fill the password in two different fields?

@Joy_1P it doesn't happen on every site, but I have noticed it on a few. I do see it pretty consistently on the AWS gov site (https://signin.amazonaws-us-gov.com), but I have also had it happen on a few other sites. I upgraded to 8.9.8, and the behavior still occurs.

By "fills twice" I do mean it fills the password field twice. The behavior is it: 1P fills the form, there is a brief delay, then 1P fills the password field again.

Hi @nickfromdc,

Thank you for confirming this.

I have tested the AWS gov site and I can't seem to replicate the behaviour. Can you let me know the steps you are taking to fill? Are you clicking on the item beneath the field or are you using a keyboard shortcut?

Any information would be really useful.

I have this issue too on multiple sites. This is the website I just had the issue with: https://moneybird.com/login
My flow and info:
- firefox latest update, 108.0.1, 1password 8.9.12, BETA channel, addon version 2.5.1
- enter the website in a new tab
- command-\ (my shortcut for 'fill')
- username and password fill both; in the password field I see the amount of stars corresponding to the length of my password
- within one or two seconds, the amount of stars doubles

Additional:
- 'inspect elements' after the 'doubling' shows it concatenates the correct password to itself, actually filling the field twice
- if i submit within the 2 seconds (i.e. before the 'doubling') login works fine
- This doesn't seem to be predictable - i.e. logging out, closing the tab, doing it again doesn't always show the same behaviour
- I have this on multiple sites
- If I do command-\ again after the doubling, the original password gets entered again, and the doubling does not occur

Hey everyone,

I'd like to pitch in as well. I'm having this issue with multiple websites (my university's websites, facebook, stackoverflow, ...) where my password gets filled in twice on autofill. This behavior only occurs when 1Password is locked and I am using TouchID or my password to unlock the app. The username gets entered correctly, the password is entered correctly but after a short delay is entered a second time in the same field which leads to unsuccessful login attempts.

I am using Firefox (108.0.1) on a MacBook with OS 12.5, 1Password 8.9.11, and Extension Version 2.5.1.

I've also noticed this on Facebook (and other sites I can't remember, unfortunately): the password is entered twice (so password1 becomes password1password1), but I unfortunately don't have any reproduction steps as it's only happened once or twice. @leonj might be onto something with 1P needing be to locked.

It is hard to reproduce, but there's something funky going on with the extension's filling behaviour related to double / twice inputting passwords.

Info:
Edge 108.0.1462.54 (Official build) (arm64)
1Password Edge Extension 2.5.1
macOS 12.6.2 (M1 MacBook Air)
1Password for Mac 8.9.11 (80911019)

I am having the same behavior. It only happens when unlocking 1Password. So starting fresh from waking the computer, I go to a website push CMD + \ (unlock 1P + fill). It prompts me to use my touch ID fingerprint. Then the password fills, the login and password fields are a slight blue shade to indicate that it has been filled. Then the password field goes white and the password doubles in length.

This only happens the first time unlocking 1P like described above. The rest of the time that it's unlocked it behaves normally. I can also hit CMD + \ after the double fill to refill the correct password.

Firefox 108.0.1
1Password Firefox Extension 2.5.1
MacOS Ventura 13.1
1Password for Mac 8.9.11

@nickfromdc, @rvdm, @leonj, @ikjadoon, @JimShady99,

I apologise for the trouble, we have done some testing and have been able to re-create the same behaviour you shared. It looks like the behaviour is limited to Firefox only, and happens only when 1Password is locked. If 1Password is unlocked when we try and fill with Cmd + \, the fill acts as expected. I've created a report to have our development team look a little further into what might be going wrong, and I've added your insights in support of this investigation.

In the meantime, could you try the following workaround to fill your login (when 1Password is locked)?

1. Navigate to the website you'd like to fill.
2. See that 1Password is locked.
3. Press Cmd + Shift + Space to invoke the Quick Access prompt.
4. Unlock your 1Password account.
5. You should then see the Quick Access prompt, press Return on your login item listed to autofill on the webpage.

I realize this extra step might not be as ideal as using the Cmd + \ to fill, and I'm sorry for any interruption in your workflow. Let us know if you have any questions!

In my experience, doing a second cmd+\ after unlocking is less work, and fills the password only once. This 're-fills' the password field with a single password. Hope that helps :)

Thanks @rvdm, I'm sorry for the trouble!
