Bro please help me. I saw a project made by you. (Named author sanjeev) it is a chat app. You told there, the package name and the firebase account must be changed. I changed it. Read and write was true. But i cant send messages to it. Usernames still not updated. Please kindly help me to solve this problem plz :(

brother, so this is the rule that I made



{

"rules": {

"user": {

"$ user_id": {

".read": "$ user_id === auth.uid || auth.uid == 'zJmj8O14lTRNTiAcF2NhDtA7Z2p1'",

".write": "$ user_id === auth.uid",

}

}

}



}



so I want 'zJmj8O14lTRNTiAcF2NhDtA7Z2p1' to be a user who can read all the data that other users have created, but it doesn't work and still every user reads their own data and a user with auth id zJmj8O14lTRNTiAcF2NhDtA7Z2p1 is only able to read his own data

hello sanjeev, maine auth!=null,diya hai chalega na,
auth.uid!=null nhi diya

".read": "true"
".write": "true"
}

Hi can you make firebase rules with expiration in account or log in expiration

Yesss helpful !

hi Sanjeev,
we haven't seen your tutorial for a long time, we really miss it...
We've just tried your firebase tutorials..
the question is, 

how to make "security rules" to our firebase.....
so that each user can only access "their own" data?
because, every time I change it with rules: {auth id = uid blah3 (as in firebase documentation) I can't access or write my data ...
Like "PROFIL" in this video example, we don't want anyone can change (write) other's profile..

Please help

what if i want to make sure every user that signs up, Has a seperate database.. having their own seperate data

kindly past in description

supper !!!!!

sir plz send your What's up no.
