What stupidly easy tech solution do people gloss over all of the time? (kbin.melroy.org)

For me it's the paranoia surrounding webcams. People outright refuse to own one and I understand, until they go on and on about how they're being spied. Here's the secret - unplug the damn thing when you think you won't use it or haven't used it in a while.

They, whoever it is, can't really spy on you on something that's already off and unplugged!

I think I'm confused on your point.

I interpreted your statement to mean "adding a requirement for certain types of characters will decrease the number of possible passwords compared to no requirements at all", which is false. Even in your example above, with only two letters, no numbers / special characters allowed, requiring a capital letter decreases the possibilities back to the original 676 possible passwords - not less.

Perhaps you're trying to say that passwords should all require certain complexity, but without broadcasting the password requirements publicly? I suppose that's a valid point, but I don't think the tradeoff of time required to make that secure is worth the literal .000001% (I think I did the math right) improvement in security.

No it doesn't. It reduces the possibilities to less than the 52x52 possibilities that would exist if you allowed all possible combinations of upper and lower case letters.

You are confused because you only see the two options of enforcing or not allowing certain characters. All characters need to be allowed but none should be enforced. That maximizes the number of possible combinations.

No, because that's still the same. An attacker can find out the rules by creating accounts and testing.
