🚨 New research from ETH Zurich has found that popular password manager's zero-knowledge encryption claims don't fully hold up if their servers are compromised.

Dashlane & Bitwarden promptly issued fixes.

LastPass did not issue a fix and stated: "our own assessment of these risks may not fully align with the severity ratings assigned by the ETH Zürich team."

In 2022, LastPass experienced a breach that impacted 1.6 million users due to inadequately strong technical and security measures within their infrastructure.

The best time to switch from LastPass was yesterday; the second best is today. ️

Here's what we recommend ️

@privacyguides A better name for LastPass is LostPass

@privacyguides This sounds like the kind of thing that cannot just be "fixed". As far as I can tell, *all three were lying* about their servers being dumb storage without access to your secrets. This is a problem of vendor integrity not a technical problem.

@privacyguides
Do you have another source for Bitwarden havin fixed the issues? If i am not mistaking, i can't see where they say something explicit about Bitwarden fixing these issues in the linked article.

@dalias @privacyguides Self-host, some things are better of self hosted. And a password manager is one of them. And better without any internet access, your devices can sync when they are on your local network.

[dalias@hachyderm.io]

@h0m3 @privacyguides It doesn't even need self-hosting. It just needs the storage backend to be a pure content-agnostic storage backend for opaque encrypted data, not having some control channel interaction that puts the vendor in a privileged position and locks you in to using their cloud infrastructure.

@dalias @h0m3 @privacyguides KeePass is the best option if you don't need cloud sync

[dalias@hachyderm.io]

@helloclippy @h0m3 @privacyguides Cloud sync is good, but only if it's *your choice* of storage and the storage provider doesn't have backdoor access to the password manager.

[h0m3@mastodon.social]

@dalias @helloclippy @privacyguides Yes. Bitwarden allows you to cloud sync to your instance, even using an alternative server application like vaultwarden. Thats the most important feature for me and i would abandon them if they choose to remove it in the future.

"Its open source but you can only connect to our proprietary servers" is a no-go to me
