Make button only be able to be clicked once

[magazine]

I have a button that will allow user to create user login, and then redirect to a new page. However, I have seen it happen that user clicks the button multiple times, creating multiple accounts in the database.

1. Is there a way to make the button to be clicked once
2. or delayed on how often it can be clicked
3. or make it disabled so not clickable again.

1. Set a custom state that is a yes/no value.
2. Set default value to no
3. when button is clicked set the state value to yes
4. conditional on the button for when the custom state value is yes, property to change, this element is not clickable and check the box
