Chrome autofills username into random text input
Solution 1
The answer is to add an invisible text input to the asp.net form called "username".
Several years ago we were having the same problem with a different input. The answer was to add an invisible input of type "password", as explained in this SO answer, scroll down to the phrase "It is so simple and tricky...":
Below is the complete fix, I added these two elements inside the form element in our site's master page. Per @Jeff_Mergler's comment below, put these inputs at the top of your form tag:
<input type="text" id="username" style="width:0;height:0;visibility:hidden;position:absolute;left:0;top:0" />
<input type="password" style="width:0;height:0;visibility:hidden;position:absolute;left:0;top:0" />
Solution 2
I was facing the same issue, i found a fix by wrapping my div inside a form tag and added a property autocomplete="off" in the form tag.
...... .....Solution 3
Some more ways to try to workaround this:
- Add
autocomplete="off"
to the<form>
and/or to the<input>
- Change the field's
name
/id
to something that does not have "name" or "user" in it - If it is not already inside
<form>
wrap the element with empty<form>
tag - Randomize the name attribute of the input, or use
data-name
instead ofname
. You'll have to change the code that process the data accordingly.
Also I think it'll help to report this issue to Google via ⋮→Help→Report an issue
(or Alt+Shift+I) to encourage them to fix these issues.

This is happening on an asp.net webforms application, using Chrome Version 72.0.3626.109 (Official Build) (64-bit).
The site is password-protected. The user logs in with a username and password. After a successful login the user is redirected to the "Loan Search" page. The Loan Search page contains a handful of text inputs.
The problem is Chrome will autofill my username into one of the text inputs (see image). "tregan" is the username I entered into the login page.
Chrome always selects this particular text input to autofill the username ("Contact Mailing Address"). This is happening to myself and several dozen other users of our web site.
Any idea why Chrome is doing this autofill, and is there anything I can do to prevent it? I cleared my Chrome autofill cache, but that did not fix the problem.

dvo about 5 yearsChrome does this by default to try to help users fill out forms. You can control this in ASP by adding
autocomplete="off"
to your ASP:TextBox declaration or you can add it to your code-behind by doingTextBoxID.Attributes.Add("autocomplete", "off");

Tom Regan about 5 years@dvo, I don't want to turn off auto-filling. I want Chrome to stop auto-filling my username into this particular field. It seems inexplicable.

EpicVoyage about 5 yearsThanks for the comment. I am seeing this also, but google is intentionally ignoring autocomplete="off". This is happening for me on fields which do not have name/id with "name" or "user" in them. The fields are wrapped inside
<form>
tags.data-name
could work for fields handled w/ AJAX calls. -
Jeff Mergler almost 5 yearsWorks! Note: this only worked when I placed the elements above at the very top of the form element before all other elements. It failed to work when placed them at the bottom so make sure to put them right below opening form tag.
<form ... > <input type="text" id="username" style="width: 0; height: 0; visibility: hidden; position: absolute; left: 0; top: 0" /> <input type="password" style="width: 0; height: 0; visibility: hidden; position: absolute; left: 0; top: 0" />

Gavin about 3 yearsI can't believe we're having to do such messy workarounds like this just to prevent Chrome from autofilling a field. It's turned into such a horrible browser.
