- 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.



This struck me as wrong, because that would be a technically impossible and liability-inviting thing to promise.
And after checking the homepages of the 3 services they tested, yep, none of them promise “absolute security.”
