Normally it is recommended to setup a SSH key with your Git hosting tool with choice. Though if that is not practical, another way you can avoid having to put in your git username and password every time you push your code is to make use of Git’s credential store.

To enable it globally across your projects

git config --global credential.helper store

Then you can edit the file ~/.git-credentials with the following format

https://username1:password1@site1.com
https://username2:password2@site2.com

It is recommended to set your .git-credentials file with the same permissions you would see in a SSH private key file. Read and write permissions for the user only.

chmod 600 ~/.git-credentials
