I already enter a passphrase every time I want to use Signal; I use the Molly client on my phone. It's really not a big deal. I also enter a passphrase every time I launch my password manager, every time I launch my two-factor authentication app on my phone, and every time I open my email client. I think it's fairly standard to protect sensitive data on your computer with encryption at rest and to decrypt it upon launching the application that handles the data.
Huh. I would've thought most desktop users just leave it running all day long like I do. Obviously there is the disk encryption passphrase at boot, adding another one for signal would in my case be redundant.
But the point is not only how easy it is to enter a passphrase, but also how much security that actually gains you. I don't think it does much on the typical desktop, be it windows or linux, where there are so many ways to escalate or persist privilege for anyone that has user-level access.
I also have full disk encryption, but I still have some databases on my disk encrypted because I decrypt my disk when I boot my computer. But yeah if you have Signal open (& its db decrypted) all the time it would probably be minimal. I don't have Signal open all the time though, only when I want to check messages or am actively using it
The point would be encryption, even the root user wouldn't be able to read encrypted data if they don't have the passphrase
If you have root, intercepting all the user's keystrokes is trivial.
