Git shell prompts for password in an OpenSSH popup window

I don't know why, recently git shell asks me for credentials in an old-fashioned OpenSSH window (by the way, I use a https connection) instead of just prompting in the console.

That prevents me to use the wincred, I always have to type my credentials. Quite annoying, esecially that when I make a typo, the console cursor disappears. How can I go back to the default mode?

System: Windows 7
Console: ConEmu

Thanks for help!
