关于github仓库建站的一个问题

自己弄个博客走到github仓库建站

echo "# 我的用户名.github.io" >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/我的用户名/我的用户名.github.io.git
git push -u origin master
输入完这些后
remote: Support for password authentication was removed on August 13, 2021.
remote: Please see https://docs.github.com/en/get-started/getting-started-with-git/about-remote-repositories#cloning-with-https-urls for information on currently recommended modes of authentication.
fatal: Authentication failed for 'https://github.com/我的用户名/我的用户名.github.io.git/'

我搜了一圈也没找到合适的解决方法,这是在mac端运行的不知道帮帮忙看一下
