Turn a user story into test cases

Write the test cases you would derive from this user story (a short description of a feature, written from the user's point of view) and its acceptance criteria (the conditions that must be true for the story to count as done).

As a registered user, I want to reset my password by email, so that I can sign in again.

Acceptance criteria:

• The reset link is valid for 30 minutes.
• The new password must be 8 to 64 characters and contain at least one digit.
• A link can be used only once.
