VULNERABILITY DETAILS
Saved password length is visible in the password manager  

VERSION
Version 63.0.3239.132 (Official Build) (64-bit)
Operating System: [Windows, Windows10]

REPRODUCTION CASE
The length of the password which is stored in the system is the first way to hack the password.For example if i have saved my password by mistake in the public internet center then it might lead to compromise of my account. In case of home it might lead to lose of privacy i have also included the screenshot of the place where i found this thing.

I have uploaded 1st step image in which we can disable the show icon option.

If the particular link is clicked then the page is opened with the store password like the image i have attached as "Before password show" then password can be view by changing the value in inspect element as "After Password Show" in the image its better to disable this option in the chrome for save password to improve the security.

if its possible i can also give the clear detail on this in the upcoming mail if you guys are interested but from my view this is one of the bigger security bug.

I have also raised the same  bug 14  weeks back but its closed.
Have also included the images through the following mail please mail back for more detail.
