# Account registration

Most dapps require users to create an account before they can do anything. Registration is handled by the [Chromia FT4 library](https://docs.chromia.com/build/ft4/intro/) (Flexible Token 4), Chromia's standard for account and token management.

You can choose from three registration types: **Custom**, **Open**, and **Transfer**.

* **Custom**: You write the registration logic yourself, using the `create_account_with_auth` function.
* **Open**: The `open` strategy registers accounts quickly and charges no fee, which makes it a common choice during development. In production, be careful with it, because anyone could abuse it to spam the network. This strategy uses the `register_account` function.
* **Transfer**: The `transfer_subscription`, `transfer_fee`, and `transfer_open` strategies are templates you configure for your dapp. They rely on the transfer function: a sender transfers a designated amount of tokens to a new account and pays a fee, which starts the registration process. If nobody claims the non-activated account within a set period, the sender can recover the tokens. The `transfer_open` strategy is the exception, as it registers accounts without charging a fee.
