解決 GitHub 無法 push，出現403問題 ( Git Push To Repository Key Username and Password Error )

介紹如何透過 GitHub Personal Access Tokens 解決 MacOS 無法 push 出現 403 問題

前言：使用 MacOS 搭配 GitHub 推送 Code 至 Repository 遇上需輸入帳號密碼驗證，但輸入正常可登入 GitHub 帳密後卻始終出現
fatal: Authentication failed for ‘ https://github.com/<userName>/iOSAppDev.git/ '

MacBook-Pro:Development appdev$ git push -u origin main
Username for 'https://github.com': <your github user name>
Password for 'https://austin7l@github.com': <your github user password>
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/austin7l/iOSAppDev.git/'

Step 1 : 確認 remote 是正確的

MacBook-Pro:Development appdev$ git remote -v
origin https://github.com/Austin7L/iOSAppDev.git (fetch)
origin https://github.com/Austin7L/iOSAppDev.git (push)

2. setting 頁面選擇 Developer settings
3. 於 Personal access tokens 選單中選到 Tokens ( classic )
4. 建立 New token，點擊 Generate new token ( Generate new token ( classic ) )
5. 輸入 Note、Expiration、Select repo scopes
6. 點擊 Generate token，會自動產生一個 token
7. 複製 Token 回到 Terminal 重新 Push
8. 輸入 Username 和 Password，密碼使用剛複製的 Token

MacBook-Pro:Development appdev$ git push -u origin main
Username for 'https://github.com': <your github user name>
Password for 'https://Austin7L@github.com': <paste the token what you create>
