Today i’ve downloaded google chrome version 78 and found that flags for importPassword is missing. To enable this features on Windows 10, here is the step:

1. Create google chrome desktop shortcut
2. Right click and go to properties.
3. In the target section just add this code at the end without quotes
” –enable-features=PasswordImport”
4. Apply and run it.
5. Now you see import option in the 3 dot menu in your password section of your chrome.

Now its works!
