# Lifecycle

The CIAM lifecycle.

> For the index of this section of the site, see [llms.txt](https://fusionauth.io/docs/llms.txt)

There's a lifecycle for CIAM users:

1.  Users must get into your identity store somehow. You can [migrate them to the new system](https://fusionauth.io/docs/lifecycle/migrate-users.md) if they exist elsewhere, you can create them via APIs or federation, or they must [self-register](https://fusionauth.io/docs/lifecycle/register-users.md).
2.  After users are in the CIAM system, they need to [authenticate, log in or sign in](https://fusionauth.io/docs/lifecycle/authenticate-users.md) (these all mean the same thing). This includes all manner of authentication methods:
    *   passwordless options such as passkeys and one-time passwords
    *   Identity Providers such as Google or Facebook
    *   SAML and OIDC federation
    *   and more
3.  User profile data also needs to be [managed over time](https://fusionauth.io/docs/lifecycle/manage-users.md). Functionality for this part of the lifecycle includes forms used by customer service reps, self-service account/profile management, searching to extract user data in bulk, and verifying users.
4.  Finally, users are sometimes de-provisioned. In FusionAuth this is done by locking user accounts by [deactivating or deleting users](https://fusionauth.io/docs/apis/users/delete.md).
