I need the information stored when logging in instead of being rewritten on the variable in Firebase, I need them to create new variable lines in the database, does anyone know how I could do this? ---

Hello @Batata2121 Welcome to the community The variable names are the issue. For example, you can save data related to a user account under the user’s unique user ID, which is generated when the user signs in to your app. This way, each user’s data is stored under a unique identifier, preventing overwriting of existing variables. ![image - 2024-05-01T183630.228](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/1/61e515d454cb89e93ecc803d7f8f71c00757d20d.png) ---
