Lastpass: How to Get Autofill Working with Native Authentication Follow



  • Avatar

    This doesn't work because LastPass won't pull up the password associated with the host-mapped domain.

    Hi Jeremy, 

    This is an older tip - you're correct.  If you're host-mapped, we no longer authenticate you against the domain (this dates back to when all Support agents needed to auth against  

    If you associate your LastPass to your host-mapped URL, it should now work as expected.

    Even using my host-mapped URL it is not working for me.


    Added 2 URLs:


    Always get this prompt and it never auto-fills:

    Hi Kevin,

    Thanks for the updates on this. I've seen this happen before myself with another piece of software I use and Lastpass wasn't filling in the login fields for me when I clicked on it to do so. I later discovered that I needed to install the LastPass web browser extension for the clicking action to work properly and the fields become filled out. 

    Are you able to confirm if you have the LastPass web browser extension installed on your browser? If not, are you able to please try installing the extension and then giving this another go from there? Hopefully that will do the trick for you and the fields will autofill like you are looking for. :)

    I would like to share that I have the same experience.  I do have the LastPass extension installed in FireFox and Chrome.  I experience the same behavior, I must search out my password and paste it in the field.

    I have several Zendesk accounts.  My company uses Zendesk for our support tickets, I am an agent there.  A company we represent uses Zendesk to track issues, I am a User there.  Nixplay uses Zendesk, I am a User on their instance, the list goes on.

    Anyway, it is just very tricky.  I would love to know exactly which URL I should place in my LastPass entries so autofill would work.

    Thanks in advance.

    Hi Martin!

    In my test account, I just have entered in LastPass (Chrome extension), and it autofills my credentials there with no problem. I double checked and verified that Chrome's native password manager was disabled, as well.

    Have you checked to make sure that your browsers and the extensions are all up to date? That's the only thing I can think of...otherwise, do you use SSL or any two-factor authentication for any of those accounts?

    Hi Jessie,

    Thanks Nataliya for opening the ticket.

    Jessie - A few factors to share. I use Firefox more these days than Chrome. I have everything up to date. I do have numerous subdomains with which I interact. I have recorded a video and uploaded it to Google Drive. The link is below. I am less concerned about autofill than I am just being able to fill in the webpage at all from LastPass. Also, please understand that I am not sure this is "your issue". It may be a LastPass issue. I do appreciate the help and the time to look at the issue.

    Here is the video.

    I look forward to your thoughts and direction.

    With regards,

    Hey Marty!

    Based on my own experience I feel like it might be a LastPass thing. I watched your video and I've had the exact same thing happen on other sites (not Zendesk). But hopefully Nataliya will be able to help you get it nailed down!

    I have been frustrated with this for a while so decided to investigate. 

    LastPass will be blocking the auto-fill as the domain you are accessing to login to zendesk does not match the domain the login widget seems to be served from. If you open your browser devtools (F12) you will see a console error.

    In my case i was accessing support.[company] whilst the login widget was served from [company] LastPass rightly protects you against this.

    I don't know if this is a misconfiguration on my companies part (I don't control this) or a flaw with how the login widget is implemented in Zendesk so it would be great for any clarification.

    However you can work around this by:

    1. Adding equivalent domains in LastPass. See here.
    2. Adding a LastPass entry for the domain serving the login widget.
    3. Clearing your LastPass browser extension cache.

    Hope this helps.
