No showing the password as it is sensitive, but I checked and they are identical.

Thanks for the report!

When you hover over the hostname, are those links for different URLs (in particular, please check the scheme).

Maxim, should the de-duplication logic in PasswordManagerPresenter have merged these two together?

Yes, I checked that and they are both for https://www.dropbox.com/1/connect

Yes, it seems that the entries should have been merged. Looks like a bug. 

Thanks for reporting, sdefresne@.

But I have no idea what happened...

1. What is OS? What is the version of Chrome? The UI on screenshot looks like it is old UI (no Auto Signin checkbox). 

2. Could you output the variable "key" right before the return statement in CreateSortKey(https://cs.chromium.org/chromium/src/chrome/browser/ui/passwords/password_manager_presenter.cc?q=CreateSortKey)? And provide the console output.
It will output unhashed passwords! Replace them with "???" or so. 

This is the current stable version on Mac (50.0.2661.102). I also have duplicates on my Android device though (running version 50.0.2661.89).

I'll try to get the value of key, but I do not have a build of Chromium available at the moment.

Password entries deduping is since 51. Please check how it works in dev channel. Thanks.

Best regards,
Maxim

Updated desktop to M51 and the duplicate entry disappeared. Thank you.
