Password manager

A password manager is an app that creates, stores and fills in strong, unique passwords so you only have to remember one main password.

What it means for you

It helps reduce risk because each account gets its own password, so one leak does not open every account. Free built-in options from Apple and Google, and free plans from Bitwarden and Proton, are covered in our household guide.
