http:// & https://

The main difference between http:// and https:// is, It's all about keeping you secure

HTTP stands for HyperText Transport Protocol, which is just a fancy way of saying it's a protocol (a language, in a manner of speaking) for information to be passed back and forth between web servers and clients.

The important thing is the letter S which makes the difference between HTTP and HTTPS.

The S (big surprise) stands for "Secure".
If you visit a website or webpage, and look at the address in the web browser, it will likely begin with the following: http://.

This means that the website is talking to your browser using the regular 'unsecure' language.

In other words, it is possible for someone to "eavesdrop" on your computer's conversation with the website.

If you fill out a form on the website, someone might see the information you send to that site.

This is why you never ever ever enter your credit card number in an http website!

But if the web address begins with https://, that basically means your computer is talking to the website in a secure code that no one can eavesdrop on.

You understand why this is so important, right?

If a website ever asks you to enter your credit card information, you should automatically look to see if the web address begins with https://.

If it doesn't, there's no way you're going to enter sensitive information like a credit card number

The passwords are the keys we use to access personal information that we've stored on our computer and in our online accounts.

What makes a strong password?
To an attacker, a strong password should appear to be a random string of characters. The following criteria can help our passwords do so:

Make it lengthy
Each character that we add to our password increases the protection that it provides many times over.
The passwords should be 8 or more characters in length; 14 characters or longer is ideal.
Many systems also support use of the space bar in passwords, so we can create a phrase made of many words (a "pass phrase"). A pass phrase is often easier to remember than a simple password, as well as longer and harder to guess.

Combine letters, numbers, and symbols
The greater variety of characters that we have in our password, the harder it is to guess. Other important specifics include:
Use words and phrases that are easy for US to remember, but difficult for others to guess.
The easiest way to remember our passwords and pass phrases is to write them down.
Contrary to popular belief, there is nothing wrong with writing passwords down, but they need to be adequately protected in order to remain secure and effective.
In general, passwords written on a piece of paper are more difficult to compromise across the Internet than a password manager, Web site, or other software-based storage tool, such as password managers.
