Just got done investigating a spambot we had earlier, and it looks like they used a lot of compromised accounts on other instances to give their post an initial upvote boost. If you don't already, please remember to use a good strong password. Keeping your account secure helps reduce spam across the whole of lemmy, and keeps your account from getting banned for things you didn't actually do.
I recommend Diceware! I use it in my professional capacity as an IT/Security person, and also you get to use your mathrocks!
EDIT: Oh, also, all that numbers and symbols shit is no longer considered good practice. Just make it a really long collection of random words, at least 12, ideally 16+ characters. And make sure the words are actually random; your 3 favorite sports teams isn't good enough, which is why I recommend diceware.
Well good news then, because even throwing every quantum computer currently on the planet is not enough to factor 2048-bit RSA, and likely won't be in any currently alive human's lifetime.
Maybe with current quantum computers, but human technology tends to increase at an exponential rate so I doubt it will be long. Scientists are already trying to design post-quantum encryption for this very reason.
