How to allow permission to my new github account

Here is your problem:

$ git config --get remote.origin.url
https://github.com/aliesoft/alienspine.git

You are using the HTTPS protocol. You can try to use public and private RSA keys to access your git repository. A tutorial on how to generate and add your public key to your profile can be found here: https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

After setting up the SSH key, try to push your code to git@github.aliesoft/alienspine.git. Change your remote origin with:

git remote set-url origin git@github.com:aliesoft/alienspine.git
