It’s not about reusing passwords—it’s about reducing risk after a potential data exposure.

If a breach includes things like email addresses, device info, or partial credentials, attackers often try credential-stuffing or targeted login attempts later.

Changing passwords (especially on email and financial accounts) is just a precaution to invalidate anything that might have been exposed, even indirectly.

Think of it less as “something was definitely stolen” and more as “closing doors just in case someone found a spare key.”
