# Determining whether users can create accounts

By default, the Tonic Structural login page provides an option to create a new Structural account.

Any user who has access to the Structural URL can create an account.

On a self-hosted instance, to prevent any new accounts, set the [environment setting](https://docs.tonic.ai/app/admin/environment-variables-setting) `TONIC_DISABLE_ACCOUNT_CREATION` to true.

You can configure this setting from **Structural Settings**. So you can set it to `false` whenever a user needs to create an account, and then set it to `true` to once again prevent account creation.
