In your Thunkable project, add a “Realtime DB component” (available in Snap to Place projects) or use cloud variables in the Drag and Drop editor. It really does depend on what program you are using. ---

There can also be another way in which I suppose replacing @ and . with any other application symbol or with just “\_” could work. I’m not sure although… The JSON code: ```auto { "Data": { "exampleKey": "exampleValue", "users": { "work7002_gmail_com": { "email": "work7002@gmail.com" }, "school7002_gmail_com": { "email": "school7002@gmail.com" } } }, "organization": { "kuro": "sfjg" }, "thunkableAccess": true } ``` What block shall I use? This way, i suppose, reading data would be easier? ---

I already added a “Realtime DB component” @krish0 I can easily input data, the thing is I’m unable to read it properly… ---

Alright! So, after 2-3 days of struggle, I figured it out, that MAYBE the thing I was talking about, was way more complex. > Getting value and find it’s key. Since every userID is unique, and unpredictable, it will NEVER work. I tried creating a new userID according to email, replacing every “@” and “.” with “\_”. and then fetched data and use code to check if “schoolwork702\_gmail\_com” existed or not. and guess what! IT WORKED! - blocks: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/4/d42c971aac076d53d8c552dd8c0012abdcd47956.png) and it will answer No/Yes accordingly! Now if a user tried to register again, it will firstly check if userID (same email is in use or not) and it I can now control is user have an account from same ID or a new one. NOTE: I’m using signing with google. ---
