首先，我已经检查过。我没有找到任何答案。我正在使用 Firebase 身份验证制作 Android 应用程序。我正在遵循有关添加身份验证的教程。我知道我已经使用正确的密码创建了用户。当我输入密码时，登录总是失败。

最佳答案
以及文档； 如果您尚未将应用连接到 Firebase 项目，请从 Firebase console 执行此操作。 .
启用电子邮件/密码登录: 在 Firebase console ，打开身份验证部分。 在“登录方法”选项卡上，启用“电子邮件/密码”登录方法，然后单击“保存”。
如果你已经这样做了， 在 Google Cloud Console 中启用“Identity Toolkit API”
最后的建议是在您的 Android 应用程序中使用 Identity Toolkit。虽然，
The newest version of Google Identity Toolkit has been released as Firebase Authentication. It includes upgraded client SDKs, open source UI libraries, session management and integrated email sending service for forgotten password flows.
New projects should use Firebase Authentication. To migrate an existing project from Identity Toolkit to Firebase Authentication, see the migration guide.
