Invalid credentials for 'https://repo.magento.com/packages.json'

Hi guys,

Is it a temporary problem or maybe something has changed about authentication?

I'll answer myself

I used to keep one pair of keys in the repository all the time. And what?
Magento Connect was pulled in by Magento Marketplace and all were removed.

Thank you Magento for informing
