A strong user base will define the strength and longevity of your website. But before acquiring valid users, you need to verify that the data submitted from the registration form corresponds to your requirements. To make this process easy, SpringBuilder has a special option to add custom validations to each registration field.

To add your special requirements, go to the User Account settings > Form > Registration Fields, choose the corresponding field and in the settings turn on the Custom Validation switcher.

Rules may vary with the validation you add to the fields. 💡
