How do I disable password prompts when doing git push/pull?

Generate a private/public key pair for password-less authentication.

For Linux, your keys are stored in ~/.ssh.

If you already have files in ~/.ssh that's named id_rsa and id_rsa.pub, then you already have a key pair. Append the contents of your public key (that's id_rsa.pub) to the Git repository's ~/.ssh/authorized_keys file.

$ scp ~/.ssh/id_rsa.pub [email protected]:id_rsa.tmp
$ ssh [email protected]
$ cat id_rsa.tmp >> .ssh/authorized_keys

If you don't have the key pair, generate one with

$ ssh-keygen -t rsa

Run

git config credential.helper store 

This will store your credentials in a folder inside root. You need to run git pull/git push after this command and give the username and password for the first time. After this, it will not prompt for username and password. Details at https://git-scm.com/docs/git-credential-store

As 0xc0de wrote in a comment, this will store the password unencrypted!

I had created a new branch and after that when I pulling, I had to enter the user name and password. Then I resolve the problem re-cloning the branch with ssh address (which is on the relevant repository site).

For example:

git clone [email protected]:sshare/GLE.git

The default caching time is 900 seconds (or 15 minutes), after which Git will prompt you to enter your username and password again. You can change it as follows (1800 seconds = 30 minutes or 3600 seconds = 1hour). ($ represents the shell prompt as a normal non-elevated user)

$ git config --global credential.helper 'cache --timeout=18000'

OR

$ git config --global credential.helper 'cache --timeout=36000'
