Permanently authenticating with Git repositories

Using credential caching

Windows

 On Windows you can use the application git-credential-winstore.

1. Download the software.
2. Run it.
3. You will be prompted for credentials the first time you access a repository, and Windows will store your credentials for use in the future.

Linux

On Linux you can use the 'cache' authentication helper that is bundled with Git 1.7.9 and higher. From the Git documentation:

This command caches credentials in memory for use by future git programs. The stored credentials never touch the disk, and are forgotten after a configurable timeout. The cache is accessible over a Unix domain socket,
restricted to the current user by filesystem permissions.

Run the command below to enable credential caching. After enabling credential caching any time you enter your password it will be cached for 1 hour (3600 seconds):

git config --global credential.helper 'cache --timeout 3600'

Run the command below for an overview of all configuration options for the 'cache' authentication helper:

git help credential-cache

OS X

Follow these steps to use Git with credential caching on OS X:

1. Download the binary git-credential-osxkeychain.

2. Run the command below to ensure the binary is executable:

   chmod a+x git-credential-osxkeychain

3. Put it in the directory /usr/local/bin.

4. Run the command below:

   git config --global credential.helper osxkeychain

Using the .netrc file

The .netrc file is a mechanism that allows you to specify which credentials to use for which server. This method allows you to avoid entering a username and password every time you push to or pull from Git, but your Git password is stored in plain text.

Windows

1. Create a text file called _netrc in your home directory (e.g. c:\users\kannonboy\_netrc). cURL has problems resolving your home directory if it contains spaces in its path (e.g. c:\Documents and Settings\kannonboy). However, you can update your %HOME% environment variable to point to any directory, so create your _netrc in a directory with no spaces in it (for example c:\curl-auth\) then set your %HOME% environment variable to point to the newly created directory.

2. Add credentials to the file for the server or servers you want to store credentials for, using the format described below:

   machine stash1.mycompany.com
   login myusername 
   password mypassword
   machine stash2.mycompany.com
   login myotherusername
   password myotherpassword   

Linux or OS X

1. Create a file called .netrc in your home directory (~/.netrc). Unfortunately, the syntax requires you to store your passwords in plain text - so make sure you modify the file permissions to make it readable only to you.

2. Add credentials to the file for the server or servers you want to store credentials for, using the format described in the 'Windows' section above. You may use either IP addresses or hostnames, and you do not need to specify a port number, even if you're running Stash on a non-standard port.

3. And that's it! Subsequent git clone, git pull and git push requests will now be authenticated using the credentials specified in this file.
