这需要在 firebase 之外完成.我将用户存储在/users/并保留他们的状态(PENDING、ACTIVE、DELETED).我有一个小型服务，可以监控处于 PENDING 状态的用户并发送确认电子邮件.其中有一个指向我创建的用于将用户状态更新为 ACTIVE 的网络服务的链接.

This would need to be done outside of firebase. I store users at /users/ and keep a status on them (PENDING, ACTIVE, DELETED). I have a small service that monitors users of a PENDING status and sends out a confirmation email. Which has a link to a webservice I've created to update the user status to ACTIVE.
