Problem with www autofilling

I have problem with autofill on mywebsite. Other works corrrect but maybe you can help me.
When I use autofill my website said is wrong password. But when I copy it’s works. It also works when after auto fill I click on password field like that. Can you help me?

@arek.ustasiak Can you provide the website you are trying to log into? Autofill looks for a field identified specifically for password. Sometimes this feature doesn’t work because the website hasn’t set up the field properly.
