firebase身份验证UID是否过期? [英] Does firebase auth UID expires or not?

问题描述

我打算在后端Web服务中将 auth.UID 用作每个用户的api_key

I'm goning to use auth.UID in my backend web service as api_key for each user

如果 UID 是最终键或它过期/更改，我会很受伤

I wounder if UID is final key or it expires/changes

推荐答案

auth.UID 将永不过期.要记住的一件事是，仅当用户不删除其帐户时， auth.UID 始终相同.如果您让用户可以删除他们的帐户，如果他们再次向您的应用程序中唱歌，则会生成另一个 UID ，它与第一个UID不同.并非每次UID都是识别用户的好方法.

The auth.UID will never expire. One thing to keep in mind is that the auth.UID will always be the same only if the user does not delete his account. If you let the users the posibility to delete their accounts, if they will sing in again into your app, another UID will be generated, which will be different from the first one. Not every time the UID is a good solution for identifying a user.
