I am having a web application where I face a vulnerability issue. When taken chrome heap memory dump, I am able to see the password which I entered on the login form. Screen shot from the heapdump is attached here.

Would appreciate of any help to get out from this issue.

1. Added autocomplete attribute to form tag, login field and password field
2. Added below meta tags under head
