Question

首先，我已经检查过了。我没有找到任何答案..我正在使用Firebase身份验证制作Android应用。我正在关注添加身份验证的教程。我知道我用正确的密码创建了用户。当我输入密码时，登录始终失败。

Answer 1

以及文献; 如果您尚未将应用与Firebase项目相关联，请从Firebase console执行此操作。

启用电子邮件/密码登录：在Firebase console中，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”。

如果你已经完成了，启用＆＃34; Identity Toolkit API＆＃34;在Google云端控制台中

最后一个提议是在您的Android应用中使用Identity Toolkit。虽然，

最新版Google Identity Toolkit已发布为   Firebase身份验证。它包括升级的客户端SDK，开源   UI库，会话管理和集成电子邮件发送服务   忘记了密码流。

新项目应使用Firebase身份验证。迁移   从Identity Toolkit到Firebase身份验证的现有项目，请参阅   migration guide。
