GitHub企业版SSO每次Git操作均提示登录，如何缓存凭证？

长期用户，首次发帖。

我已查阅过Windows系统中GitHub凭证缓存相关资料，但现有方法均无效，以下是我的问题详情：

环境信息 #

• 公司使用GitHub，强制启用SSO登录，要求使用HTTP协议执行Clone、Pull、Push操作，无法使用SSH
• 操作系统：Windows 10
• Git版本：2.47.0.windows.2

问题症状 #

每次从命令行克隆仓库时，会弹出2次“Sign In”登录窗口，完成浏览器认证后Git才能继续执行并获取代码。后续执行git pull或git push时，无论操作间隔时长，都会再次要求登录。

期望目标 #

配置凭证缓存，避免每次Git操作都需重复登录。

已尝试方法 #

• git config credential.helper store —— 无效
• git config credential.helper manager —— 无效

当前Git配置信息 #

执行git config --list --show-origin的结果如下：

请问如何配置凭证缓存，避免每次操作都需登录？自切换到GitHub后这一直是困扰我的问题。
