【问题描述】：

我正在尝试使用 ED25519 通过 SSH 连接到 GitLab，并遵循以下来源：https://docs.gitlab.com/ee/ssh/。当我测试连接并期待欢迎消息时，它不起作用并且仍然提示输入密码。我尝试了我的用户密码，但它不起作用，我不确定此时需要哪个密码。这是输出。

ssh -Tv git@gitlab.tubit.tu-berlin.de

【解决方案1】：

根据您提到的指南，您需要仔细检查：

您使用的是 OpenSSH 6.5 或更高版本
您已将公钥复制到您的 GitLab 用户帐户设置/SSH 密钥

我会先用不带任何密码的 SSH 私钥对其进行测试。
