Password managers are less secure than promised (ethz.ch)

  • Millions of people use password managers. They make accessing online services and bank accounts easy and simplify credit card payments.
  • Many providers promise absolute security – the data is said to be so encrypted that even the providers themselves cannot access it.
  • However, researchers from ETH Zurich have shown that it is possible for hackers to view and even change passwords.

Would having a synced Keepass database with a composite key protect against this?

When I made my database I created a composite key file that never goes online. I locally copy it to any device that needs to access the database. The idea was even if the password got compromised you can't access the database without the key file

What if you have a house fire and lose all devices with the key

What if there's a nuclear war end the house gets vaporized?

To protect against this scenario I have this small portable computer that I keep in my pocket. They're quite popular these days.
