Disabling Chrome Autofill
I have been running into issues with the chrome autofill behavior on several forms.
The fields in the form all have very common and accurate names, such as "email", "name", or "password", and they also have autocomplete="off" set.
The autocomplete flag has successfully disabled the autocomplete behavior, where a dropdown of values appear as you start typing, but has not changed the values that Chrome auto-populates the fields as.
This behavior would be ok except that chrome is filling the inputs incorrectly, for example filling the phone input with an email address. Customers have complained about this, so it's verified to be happening in multiple cases, and not as some some sort of result to something that I've done locally on my machine.
The only current solution I can think of is to dynamically generate custom input names and then extract the values on the backend, but this seems like a pretty hacky way around this issue. Are there any tags or quirks that change the autofill behavior that could be used to fix this?

EDIT Sept 2020: autocomplete="chrome-off" disables Chrome autofill. Original answer below.

For new Chrome versions you can just put autocomplete="new-password" in your password field and that's it. I've checked it, works fine.
Got that tip from Chrome developer in this discussion: https://bugs.chromium.org/p/chromium/issues/detail?id=370363#c7
P.S. Note that Chrome will attempt to infer autofill behavior from name, id and any text content it can get surrounding the field including labels and arbitrary text nodes. If there is a autocomplete token like street-address in context, Chrome will autofill that as such. The heuristic can be quite confusing as it sometimes only trigger if there are additional fields in the form, or not if there are too few fields in the form. Also note that autocomplete="no" will appear to work but autocomplete="off" will not for historical reasons. autocomplete="no" is you telling the browser that this field should be auto completed as a field called "no". If you generate unique random autocomplete names you disable auto complete.
If your users have visited bad forms their autofill information may be corrupt. Having them manually go in and fix their autofill information in Chrome may be a necessary action from them to take.
