Signal's desktop app stores encryption keys for chat history in plaintext, making them accessible to any process on the system
Researchers were able to clone a user's entire Signal session by copying the local storage directory, allowing them to access the chat history on a separate device
This issue was previously highlighted in 2018, but Signal has not addressed it, stating that at-rest encryption is not something the desktop app currently provides
Some argue this is not a major issue for the "average user", as other apps also have similar security shortcomings, and users concerned about security should take more extreme measures
However, others believe this is a significant security flaw that undermines Signal's core promise of end-to-end encryption
A pull request was made in April 2023 to implement Electron's safeStorage API to address this problem, but there has been no follow-up from Signal
They're thinking "This doesn't improve shareholder value, so we're not going to put it on a sprint this quarter", same as every other commercial piece of software does.
Also, this quarter becomes "ever" after about six months of it sitting in a backlog waiting.

This has actually been useful for me in the past when reinstalling my OS lmao. In an ideal world we could reverify by entering a code from our phones to unlock the desktop local storage after moving it. My biggest wish for Signal is more seamless message history movement across devices and ecosystems. Fuck even proper back ups would be nice.
My biggest issue with Signal is it being so mobile-oriented. Mobile use seems to be encouraged, and even to register you are directly told to go to the mobile app (and if you register in a VM, you're then stuck using it because it wants you to scan a QR code which is so easy to do in a VM!) No thanks, I don't trust my mobile - they're much harder to make private and "yours" than a desktop. Was it that hard to just add a field for entering the verification code in the desktop client? Sure, I did end up using signal-cli, but it is not mentioned anywhere officially. Point is about how the Signal itself tries to push you onto mobile.
Not having backups here on iOS stresses me out. I like using iOS beta updates, but knowing I’m one bad beta from having to restore my phone (where every other little thing except Signal is backed up and waiting) and lose my conversation history forever really bugs me.
