1Password Sometimes Double-Fills Password Field

Hey @henrys,

I'm sorry for the trouble, I have added you as an affected user to our internal issue. I appreciate the detail you have provided and I have passed it on.

Does the workaround I have given above help in the meantime?

Thank you for your patience!

I am also experiencing the same issue.
Firefox 109.0.1
1Password Firefox Extension 2.6.0
1Password 8.9.15

It happens approximately one in ten every password fills, when I use cmd+\

There's no real pattern I've noticed with the type of login form or site. Also, very occasionally it will happen a second time in a row. i.e. I hit cmd+\, it fills the password once then ~0.3s later the same password is entered a second time. I clear the password field, hit cmd+\ again, it fills the password once, then a second time again. I've never had it happen a third time in a row.

Also, it has happened for me with 1Password both locked and unlocked.

Hey @HomemadeToast57,

I'm afraid I don't have any news for you at this time, I have added you to the list of affected users and have asked the team for an update.

I know it's not ideal but I hope the above workarounds are useful for the time being. I'm so sorry for the disruption.

Hey! I was wondering if there were any updates on a fix for this issue. Still experiencing this bug in Firefox while auto-filling my login on my university website. Here is the url to the university login website that I can reproduce the bug in: my.binghamton.edu/. Thank you!

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

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 :)

@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!

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.

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

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.

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.
