# Manage sign-ups and sign-ins

Learn how to manage the complete Customer authentication lifecycle with commercetools.

**Learning objectives**

After completing this module, you should be able to:

- Implement the core Customer sign-up and email verification process by using the Composable Commerce API, including creating Customer records and managing verification tokens.

- Analyze various Customer sign-in scenarios, distinguishing between global and Store-specific authentication methods to enforce brand and regional boundaries.

- Develop a secure password reset workflow and a strategy for migrating anonymous user resources, such as Carts and Shopping Lists, to an authenticated Customer account.
