ELI5: Why are password manager programmes considered secure? Surely hackers then only need to access one piece of software to have access to all accounts.

With password managers, your passwords are encrypted, and are only decrypted on your local computer.  So the only way that anyone can access your passwords is if they have control of the computer you're on (via a virus or trojan horse), in which case they could already read every password you type *anyway*, even if you weren't using a password manager.
