[boost] [git help] GitHub boostorg library authentication

To test the modular boost docs I'm writing, I did this: git clone --recursive https://github.com/boostorg/boost.git modular-boost cd modular-boost ./bootstrap.sh ./b2 headers cd libs/system git checkout develop # did a simple edit of one file git commit -a -m "my bug fix" git push origin develop Everything ran as expected until the last step, which resulted in this: Username for 'http://github.com': That's a problem. Authentication needs to happen automatically. What steps did I miss? Thanks, --Beman
