And now you don't remember if you used an uppercase, or where you put spaces, or where you put a dash, or whether you used 1st or 'first', and then you're screwed, because for the hash you need you input to be byte-for-byte the same. Password management is not a technical problem. All these 'solutions' to passwords being 'insecure' massively miss the point - which is that people just forget things, especially when they need to remember dozens or hundreds of them. Use a password manager and get rid of these nonsensical hacks.
