In the latest Canary build 40.0.2210.0 there is a new flag relating to password management.
The flag can be enabled at:
The flag description is:
Show a link in the password manager settings page to manage your synced passwords online.
When enabled you should be able to select 'Manage Passwords' under Passwords and Forms in Chrome's advanced settings. Doing this you will bring up your passwords window with a link to manage passwords remotely.
The link takes you to
https://passwords.google.com/settings/passwords which currently gives a 404 error. So they are obviously still working on it.
