If you really need to use username+password (why though?), the solution is to setup it yourself using firebase function. You save the username and password yourself in firebase, and the function read and match the inputted data from firebase. If matched, you create custom firebase auth token
据我所知，firebase不提供用于登录的用户名和密码。

但是要当心，不要公开公开敏感数据，请确保将数据库设置为拒绝来自用户的所有读/写请求（仅允许您的函数提供）
