How do you define multiple sign up?

Do you mean the same user with different email addresses?

- You can’t.

Do you mean multiple sign up with the same email address?

- As long as you have User Profiles configured, Glide will automatically assign a new row in your Users table for each unique user that signs in. If the same user signs in a a second time with the same email address, they will be attached to the already created row.

Can you go into further details on why you need to prevent that from happening?
