Just published 15,000+ words on security keys. 🔐📱💻

With SIM attacks at their highest, now is a great time to take a closer look at your online security.

Removing SMS from your two-factor auth is a start, but authenticator apps have downsides too...

Just look at these headlines from recent SIM swap and port attacks.

It's all too established for attackers to find ways to socially engineer control of your phone number and start gaining control of your accounts.

I first talk about some general security tips.

Unfortunately not all websites let you remove your phone number from accounts.

You may consider migrating your phone carrier to @googlefi , which requires email account access to do anything (and can be locked down with security keys and even Advanced Protection)

Beyond SMS, I talk about issues that TOTP authenticator apps (the code generators) have as a form of two-factor auth. They're so, so much better than relying on SMS for your second factor but they still have issues like utilizing shared secrets and lacking phishing prevention.

Enter security keys!

Utilizing public key cryptography they don't have any shared secret between the client and the server. They prevent phishing by taking the website domain into account.

Even if you get tricked by a clone phishing website, your key won't.

Positioning in CSS allows you to display your element wherever you want on the screen

But when I was learning it, I found it little bit confusing😅

So in this thread I'll try to explain it in easiest manner with practical implementation. Let's start

THREAD🧵👇

There are 5 values that you can pass in position property

- static
- relative
- absolute
- fixed
- sticky

In this thread we will be focusing on relative and absolute positioning as both are widely used

Let's start with understanding what document flow is?

📌 Elements are displayed on the screen as they written in the HTML document

Consider the following piece of code:

H1, P, H3 and div are displayed on the screen in exact order as they written in the HTML file.

As now you know about document flow, let's start with Relative positioning

📌 Relative Position

- Relative positioning do not take an element out of document flow
- Relative positioning is relative to element's original position which can be changed using offset

🔹 Relative position is relative to itself.

For example: Consider the code and output in the attached image below

As you can see red box is shifted 100px from left because I applied left offset after giving it relative positioning

Been reading up a lot about these jabs, esp as I know they are going to be a condition of a return to normality

Was on a zoom call last evening with a testing company that had some fascinating evidence on protection etc.

I have more reading to do.

I do not want to be coerced into something I don't want, BUT i want normal back as soon as possible.

Basically i'm at the point in my isolation and thinking that I'll take whatever just so this bullshit can end.

That is a desperate mindset, but so is 12 months of being cut off from the world.

All i have is what goes round and round in my head.

There's no one else to help balance it.

So i'm in group 6, and my surgery are doing group 6 right now. And i am at the point i want to do it to get it DONE.

And also to study what happens. Because i have that kind of mind.

I remember Pandemrix.

But we live with risk every day.

I risk my life climbing walls with only a harness around my waist to catch me as i lean back and fall off

And rational risk assessment is at the heart of everything going wrong these last 12 months
