These are unique numbers.
You can generate with clock system time block.

timestamp?
its also good idea. but im not sure how much unique it is, no option at all that 2 users will generate the same timestamp on the same time?
just if anyone ask himself how…

Can I know why do you need this?
It will help to understand well.
I used this to make a Chat app.
Otherwise you can directly get ’ unique id ’ by this block

You can generate new ID by using random digits and then you can check them in firebase that is it present or not for every execution.

you can use

timestamp-Auth.uid*

by this you can generate unique post id for each user in your app

and also user
$postId wild card in database rules

Note timestamp should be in milliseconds

do you want to ownership of post by the user who post and only he can write?

if yes
then

        ".write" : "root.child('users').child(auth.uid).child('posts').child($postId).child('Own').val() === true ",

Builders like Kodular or Other are not supported to generate such id…

So user this method For generate it. It is quite simple but this method generate it.
Use Web Connectivity to perform this operation

To generate a unique , timestamp-based key for every child added to a Firebase database reference we can send a POST request. For our users path, it made sense to define our own keys since each user has a unique username. But when users add blog posts to the app, we’ll use a POST request to auto-generate a key for each blog post:

curl -X POST -d '{
  "author": "alanisawesome",
  "title": "The Turing Machine",
}' 'https://docs-examples.firebaseio.com/rest/saving-data/fireblog/posts.json'

Our posts path now has the following data:

{
  "posts": {
    "-JSOpn9ZC54A4P4RoqVa": {
      "author": "alanisawesome",
      "title": "The Turing Machine"
    }
  }
}

Notice that the key -JSOpn9ZC54A4P4RoqVa was automatically generated for us because we used a POST request. A successful request will be indicated by a 200 OK HTTP status code, and the response will contain the key of the new data that was added:

{"name":"-JSOpn9ZC54A4P4RoqVa"}
