git push command no longer requires a password after simple git clone

Problem:

Every time you upload the code you need to enter a user name and password, especially cumbersome. Need to be made into a form that does not enter a password.

When GitHub gets a remote library, SSH and HTTPS are available, with two different URL addresses and different authentication methods. You can no longer enter your account password when using SSH to save the key pair.

git clone git@github.com:liaopan/deepknowledgetracing.git

This will not be the password to submit again. [Provided that SSH key has been set up.] ]
