Composer: Password authentication doesn't work for Bitbucket, only SSH key possible.

[stil]

I have single private repository hosted on Bitbucket (as they offer it for free).
I added it to my composer.json as below:

{
        "type": "vcs",
        "url": "https://[email protected]/user/myprivaterepo.git"
}

Then I ran install:

PS D:\dev\htdocs> php .\composer.phar install -v
Loading composer repositories with package information

  [RuntimeException]
  Failed to clone https://[email protected]/user/myprivaterepo.git, could not read packages from it

  fatal: Authentication failed

install [--prefer-source] [--dry-run] [--dev] [--no-custom-installers] [--no-scripts] [-v|--verbose]

It works perfectly when I add my SSH key to Bitbucket deployment keys or I change composer.json to:

{
        "type": "vcs",
        "url": "https://[email protected]/user/myprivaterepo.git"
}

But I don't want to store plain text passwords in compser.json

This is a duplicate of #482, but if it works with your ssh key I would recommend just using that for now.

Why is this closed "I would recommend just using that for now" doesn't works as a solution by far.
I have a server that has disbled the connections on the that port so SSH it's not an option!
