Caching your GitHub password in Git

Turn on the credential helper so that Git will save your password in memory for some time. By default, Git will cache your password for 15 minutes.
Step 1. On the command line, enter the following:

git config --global credential.helper cache
# Set git to use the credential memory cache

Step 2. To change the default password cache timeout, enter the following:

git config --global credential.helper 'cache --timeout=3600'
# Set the cache to timeout after 1 hour (setting is in seconds)
