Realtime Database Rules

Discuss
1

I made a system just to test the firebase realtime rules but it didn’t work.
These are the rules I’m using:
{
“rules”: {
“TesteAcesso”: {
“usuarios”: {
“$uid”: {
“.read”: “auth != null && $uid === auth.uid”,
“.write”: “auth != null && $uid === auth.uid”
}
},
“cad_geral”: {
“$uid”: {
“.read”: “auth != null && $uid === auth.uid”,
“.write”: “auth != null && $uid === auth.uid”
}
}
}
}
}
This structure remained in the database:

To make this post so that this structure would appear I had to change the reading and writing rules to true.
The reason? When I set these rules and open the application on the login screen, I get a Permission Denied error.

When I click continue it lets me log in but on the next screen it gives the same error Permission Denied

I did a first registration test using the rules. The message Permission Denied appeared on the initial “Access” screen, I clicked continue. I clicked register and again the message Permission Denied appeared. I clicked continue again, filled in the username and password fields and in Authentication it let me save.

I returned to the login screen, the message did not appear. I logged in and on the general registration screen the message appeared again:

I clicked continue, filled in the fields and clicked record, but nothing appears in realtime:

the comparison operator = = =, which is not valid in Firebase rules.
Correct Rules

{
  "rules": {
    "TesteAcesso": {
      "usuarios": {
        "$uid": {
          ".read": "auth != null && $uid == auth.uid",
          ".write": "auth != null && $uid == auth.uid"
        }
      },
      "cad_geral": {
        "$uid": {
          ".read": "auth != null && $uid == auth.uid",
          ".write": "auth != null && $uid == auth.uid"
        }
      }
    }
  }
}

if it helpful mark as solution.

So, it continues to give access denied even with these modifications.
It was recorded like this:
