Please, does anyone know how to authenticate and access Firebase's Realtime database through Lazarus? Thanks

FireBIRD is not a good idea for real time or near-real time access. Use a proper database ( and yes that is expensive)
Manuals, manuals, manuals first.
You have incompetence and sheer incompetence.

Thaddy, the question is about Google's Firebase Realtime Database, not Firebird.

Since FireBase is a NoSQL-Database --> https://forum.lazarus.freepascal.org/index.php?topic=36965.0

Fortunately, Google always implements things in language independent way, despite providing easy to use wrappers for certain languages.
Rest API is the way to go. Follow all steps in that link then you can turn the cURL commands into the equivalent for fphttpclient or whatever HTTP client library of your choice. After all, that's what the wrappers do.

For instance, the example:
Code: Bash  [Select][+][-]
  1. curl -X PUT -d '{
  2.  "alanisawesome": {
  3.    "name": "Alan Turing",
  4.    "birthday": "June 23, 1912"
  5.  }
  6. }' 'https://docs-examples.firebaseio.com/fireblog/users.json'
  7.  
is equivalent to:
Code: Pascal  [Select][+][-]
  1. uses
  2.   fphttpclient,fpjson;
  3. ...
  4. var
  5.    obj: TJSONObject;
  6. ...
  7. with TFPHTTPClient.Create(nil) do
  8.   try
  9.     obj := TJSONObject.Create;
  10.     obj.Strings['author'] := 'alanisawesome';
  11.     obj.Strings['title'] := 'The Turing Machine';
  12.     RequestBody := TRawByteStringStream.Create(obj.AsJSON);
  13.     obj.Free;
  14.  
  15.     WriteLn(Put('https://docs-examples.firebaseio.com/fireblog/users.json'));
  16.   finally
  17.     Free;
  18.   end;
  19.
