I would read through the specifications on the autocomplete attribute from various credible sources.

According to w3schools, the only valid values are on or off
HTML input autocomplete Attribute[^]

According to MDN (Mozilla Deliver Network, the makers of FireFox), there is a variety of values that can be used in there; however what happens in other browsers is not guaranteed
The HTML autocomplete attribute - HTML: Hypertext Markup Language | MDN[^]

NOTE:
The autocomplete attribute also controls whether Firefox will — unlike other browsers — persist the dynamic disabled state and (if applicable) dynamic checkedness of an <<input> element, <textarea> element, or entire <form> across page loads. The persistence feature is enabled by default. Setting the value of the autocomplete attribute to off disables this feature. This works even when the autocomplete attribute would normally not apply by virtue of its type.

Now if we go to W3C (World Web Consortium), the actual standards organization; they do not have listed out actual values. What they do have which may be helpful is how the DOM has it represented: attribute boolean autocomplete, and boolean generally is accepted as a true or false.
HTML5 Reference[^]

In Summary
There are standards that can be followed and you can hope that the browser honors what you have requested. But, as evidenced by the MDN link above; browsers may extend that functionality so you never know what they do or do not support. Nevermind that many people have extensions added onto their browsers that can further interfere or augment this.

An observation
One of the heavily secured websites I sign into is using Angular Material UI design components, and they have leveraged those components quite nicely to NOT save or fill in login credentials.
You may want to browse through their write-up and code to see if this can help you out.

Solution 2

You haven't provided a lot of details, but I'm guessing you're trying to disable autocomplete on your login form.

That's a very bad idea. By doing that, you are trying to force users to choose extremely weak passwords, and encouraging them to reuse the same password across multiple sites. That's why all modern browsers will ignore autocomplete="off" for login forms.

If you're writing a "user management" page, where you can set passwords for other users, then you can use autocomplete="new-password" on the password field, which most modern browsers respect. But do not use this on your login form!

I'm trying to turn it off on a normal form for Client First Name and Country name, not in password, and the autocomplete="new-password" or anything else similar to this is not working. I'm using asp.net components.

If you're using an ASP.NET <asp:TextBox> control, you'll need to set AutoCompleteType="Disabled", which will then render the autocomplete="off" attribute for that control.

Yes i test it as well, i add AutoCompleteType="Disabled" which is render to autocomplete="off", but it doesnt stop appering of autocomplet list undet the field.

Sounds like you're getting autofill, rather than autocomplete. This deliberately ignores autocomplete="off" as a policy decision.

The only way to work around that seems to be to give the attribute a value that Chrome doesn't recognise.
