Yes and No.

Yes, everything increases in difficulty but the increases in difficulty are asymmetrical.

The difficulty of reversing a computation (e.g. reversing a hash or decrypting an encrypted message) grows much faster than just performing the computation (e.g. hashing a message or encrypting one).

That’s the basis for encryption to begin with.

It’s also why increasing the size of the problem (e.g. the size of the hash or the size of a private key) makes it harder to crack.

The threat posed by quantum computing is that it might be feasible to reverse much larger computations than it previously was. The caveat on that, however is that they have a hard limit of what problems they can solve based on the number of qbits they have.

So for example, let’s say you use RSA for encryption and someone builds a 1024 qbit quantum computer. All you have to do is increase your key size so that it would require 1025 qbits to crack, and then that quantum computer wouldn’t provide an attacker any benefit at all.

(Of course, they’d still be able to read your old messages, but that’s also a fundamental principle of cryptography; it only protects you for a period of time)

It's actually super useful for old people, who sometimes like to "accidentally log off" and stuff.

Using special terms wrongly doesn't mean I'm clueless, cryptobro.

That's how they get you, i put mine in a DONTREADME.txt file.

Or Microsoft who randomly needs to verify someone's identity before they can log into.tgeir computer but the user doesn't have a smart phone. So they need to call someone trusted to have them log into their email from a different computer just to get the code so the user can log into their computer.

But that also means they didn't have access to any saved passwords so a notebook helps.

I really should put Linux on her machine but then I have to show her how to do that too. It's a lose-lose so I keep it the same.

I miss local accounts.

You can still use local accounts with Windows 11. It's just a bit fiddley. If you use Rufus to make your boot usb, there's a bunch of deshitification options you can do.

Honestly, for at home personal use, it's better than any on device password manager. It's not hackable. Someone has to break into your home and steal it.
For an office environment though....worst way to handle it after sticky notes.

Can't wait to hand write my 32-bit passwords.

You haven't changed your password for 30 days. Reset it now.

My handwriting comes with free encryption at rest. Even I might not be able to read it.
