You use the Midaz Module to manage Account Types. Account Types classify accounts by their role in your Organization’s financial structure. When you enable validation on a Ledger, each new account must use a registered Account Type. For more details, refer to the **Account Types** section on the [Accounts](/en/midaz/accounts#account-types) page. ### Enabling Account Type validation You enable Account Type validation for a specific Ledger from the **Lerian Console**. You do not edit environment configuration files. On the **Ledgers** page, click the three dots () next to the Ledger. Select **Details**. In the sidebar, click the **Settings** tab. Toggle on the **Validate Account Type** switch. The change takes effect immediately for the selected Ledger. Enabling Account Type validation does not make the Type field mandatory — it is always required when you create an account. Instead, validation changes the Type field from free text to a dropdown restricted to the registered Account Types. ## Accessing the Account Types page *** To open the **Account Types** page, select the **Account Types** option in the **Foundation** section of the left sidebar menu. The **Account Types** menu item appears only when **Validate Account Type** is enabled for the active Ledger. If validation is off, the menu item is hidden. The **Account Types** page lists all Account Types you created for the current Ledger. **Account Type validation disabled** — If **Validate Account Type** is off, a banner appears at the top of this page. You can view and edit the registered account types. The Ledger does not validate these rules when you create accounts. To enforce the rules, turn on **Validate Account Type** in the Ledger settings. ### Available actions From the **Account Types** page, you can:
