With the recent hack, there is now irrefutable proof of malicious actors who trying to break Lemmy and steal user accounts. Please be careful about entering your password into random Lemmy apps! - lemm.ee

I think for a while leading up to the recent session stealing hack, there has been a massive amount of positivity from Lemmy users around all kinds of new Lemmy apps, frontends and tools that have been popping up lately. Positivity is great, but please be aware that basically all of these things work by asking for complete access to your account. When you enter your Lemmy password into any third party tool, they are not just getting access to your session (which is what was stolen from some users during the recent hack), they also get the ability to generate more sessions in the future without your knowledge. This means that even if an admin resets all sessions and kicks all users out, anybody with your password can of course still take over your account! Of course this isn’t to say that all Lemmy app developers are out to get you, but at this point, it’s quite clear that there are malicious folks out there, and creating a Lemmy app seems like a completely easy vector to attack users right now, considering how trusting everybody has been. So please be careful about what code you run on your devices, and who you trust with your credentials!
