问题
I am looking for an option to change domain name that is being used for real time database features like email verification / password reset. At the moment emails that are sent to users use default project-name.firebaseapp.com domain names. It would be good to use custom domains for this. I believe firebase hosting allows to achieve this, yet there is nothing about domain change for real time database.
回答1:
Email verification and password reset are part of the Firebase Authentication, so are documented/configured there.
For example: this page mentions the firebaseapp.com domain problem at the bottom (in the blue box).
The email templates (and sender address) can be configured in the Authentication tab of the Firebase Console.
