Can you explain what is meant by a user story in agile development?

A user story in agile is a brief description of a feature or requirement from the end-user's perspective. It helps the team understand the value that a particular feature should bring.

Typically, a user story is formulated as: "As a [user type], I want [goal], so that [benefit]."

For example:

As a registered user, I want to be able to reset my password so that I can regain access to my account.

This helps focus on user needs rather than technical details and serves as a basis for discussion and planning in sprints.
