Firebase Auth using phone number and password

阅读更多关于 Firebase Auth using phone number and password

I am developing Android app using Firebase. Because of that, I want to use Firebase Auth. I have following requirements: Register/Log in using Facebook Register/Log in using Email/Password Register/Log in using Phone Number/Password The first two are OK, I followed basic tutorials . However, Phone Number / Password is the problem here. Firebase supports only Phone Number/SMS Token for this (its called Phone Auth), but there is no mention about my case. I do not want to hack Firebase and use its realtime database instead of Auth 'database'. Is there any better way to achieve this? Thank you.

How to use firebase with read and write rules as false

阅读更多关于 How to use firebase with read and write rules as false

I am working on a project and I followed few tutorials in order to learn and build the app. But all of them, they change the Firebase read and write rules to true which is not safe. for example they change { "rules": { ".read": false, ".write": false } } to { "rules": { ".read": true, ".write": true } } This gives access to anyone to read and write the server data which is not safe in any way. And hence I turned this to false and now I am unable to register the user to Firebase it is giving an error saying 'Permission Denied. So what would I have to do in order to get the permission now.

accessing email address in firebase rules [duplicate]

阅读更多关于 accessing email address in firebase rules [duplicate]

This question already has an answer here: How can we guarantee that the email saved by the Firebase user is indeed his own email? 1 answer I'm using firebase 3. When writing firebase rules, the auth object only contains the uid and the provider. Is there any way that this could be enhanced to also provide the email address? The problem that I'm trying to solve is that the owner of the site I'm working on wants to permission users based on their email address, because he won't know their firebase uid up front. I have seen solutions to this suggesting to persist the user object in firebase (with

Firebase user returns null metadata for already signed up users

阅读更多关于 Firebase user returns null metadata for already signed up users

I have been using Firebase for authentication of users in the app. FirebaseAuth.getInstance().getCurrentUser().getMetadata() returns null when user comes back to the app after the sign up. It works perfectly when user signs up for the first time, but returns null for returning users. Malcolm from the Firebase Team here. Thanks for pointing this out. This is presently a bug in the persistence done by the Android SDK. We'll get on fixing this ASAP - keep an eye on upcoming release notes to know when it's resolved. In the meantime, the workaround you can use is to write to your app's

Firebase Auth saved after uninstall. How can I delete it?

阅读更多关于 Firebase Auth saved after uninstall. How can I delete it?

I've recently discovered that Firebase Auth saves itself on the device even after my app is uninstalled. I can't figure out how to REMOVE this old Auth info. I don't want a user to still be signed in after uninstalling and reinstalling the app. If for no other reason than my own testing of what I expect to be "clean installs" on the same device. I understand there is no easy way to capture an uninstall event, so I want to clear out any potential old Auth info on the first launch. So I added code (which seems to work fine) to check if this is the first launch: Boolean firstRun = prefs
