Attached: 1 image 1/3 #TechTuesday #Password I have a #TechTip for you this week about how to create memorable, #Strong #Passwords such as a mix of letters and numbers, at least 1 uppercase, at least 1 special character, etc. I got this one from a video by an actual hacker. He said to think of a memorable sentence, and abbreviate it into a password. So, a sentence like "My birthday is the 29th of February!" abbreviates to "Mbit29thoF!". So it's strong, and easy to remember! But that's only the start...
@chucker @codinghorror
"thatβs good advice for your master password" - every password, all of them unique and memorable
"you shouldnβt even _know_ the password" - what's wrong with being the only person in the whole word who knows your own passwords, none of which are written down or stored anywhere at all? π
@SmartmanApps @codinghorror making a password memorable decreases its entropy. A random password you don't have to memorize can be longer.
That's why only the passwords you really _have_ to type in by hand should be memorable.
@chucker @codinghorror
"A random password you don't have to memorize can be longer" - the only limit to the length of this one is your own imagination.
"That's why only the passwords you really _have_ to type in by hand should be memorable" - yep, solved problem. Did you even read the thread?
@SmartmanApps your thread says:
>So what we want to do is follow this same process for each place and have a memorable strong password for that place.
Do not create memorable passwords for "places". Use a password manager.
@SmartmanApps @chucker No, this is terrible advice. As SΓΆren said, you should create one password for a password manager, then all further passwords should be randomly generated and stored in that password manager. This has been standard advice in the security community for about 20 years. Password length is much more important than the variety of characters used.
As someone who deals with authentication security for a living, my master password is around 50 characters long and is made up of dictionary words which I selected randomly, then memorized.
@chucker After reading some of that accountβs recent posts, they are similarly wrong. I now suspect it to be some kind of troll. For example:
https://dotnet.social/@SmartmanApps/112711027003047449
The provided example with the division and parens is 8/2(1+3), which the poster asserts equals 1. No, it equals 16. The parens resolve first yielding 8/2*4, then multiplication and division resolve at the same time, left to right.
Similarly, the assertion 0.9β¦ it not equal to 1 depends on operating only in the space of real numbers, and 0.9β¦ is not a real number. Itβs a hyperreal, and in the system of hyperreals, 0.9β¦ exactly equals 1.

On one hand it's to provide me (and you!) with things that can be linked to, to save myself (and you) from repeating myself, but peeling back the onion on that really it's about preventing #Math #bullying, for sadly I have seen people who bully others into believing the wrong #Mathematics answer. i.e. not about who's right, but stopping the #bullies!...
