Access to GitHub only possible with

I can successfully add files to a local repository and push it to github using github desktop. When I try to commit to github using the git commandline or GitExtensions I get an error

"C:\Program Files\Git\bin\git.exe" push --recurse-submodules=check --progress "origin" refs/heads/master:refs/heads/master
remote: Invalid username or password.
fatal: Authentication failed for 'http://ift.tt/1EtNNuM'
Done

I dont have 2fa enabled. What is github desktop doing different that it can login?
