Passwords are the guardians of our online information. They safeguard (or should safeguard) every online profile you create, as well as the information included within it. Do you, however, understand how passwords work? Most individuals just know and believe that they need to know is that they type a login and password into a couple of text boxes, and a website opens up for them like a key in a lock. Understanding the mechanics of online passwords, on the other hand, can assist users in creating a strong password for improved online security. Let's take a look at the science of passwords from the inside. What is the process of creating a password?
When and why did they first appear?

How Do Passwords Work?
As a website visitor, you just get a glimpse of how passwords work. When you sign up for a website, it will usually ask you for some personal information. Name, preferred username, possible date of birth and address, as well as your password. You fill out the form, click "sign up," and then you may log in with your username and password every time after that because the website saves your information for future use.
The process behind the scenes, however, is even more complicated. While storing your information verbatim on a server is the simplest way for a website to remember it, this is hardly a secure option. If If a cybercriminal hacks or penetrates that server, your password and other information will be exposed to everyone. As a result, trustworthy websites utilize a sort of encryption known as "hashing" to filter your data.
What is Hashing?
In essence, hashing scrambles your data and assigns it a unique string of random letters and numbers. “md5()” is one of the most often used hash functions. It converts any input into a 32-character string. Below is an example of how it works:
9fgt456an2fi85anq601iq5hb6m1o0z3 md5(password) = 9fgt456an2fi85anq601iq5hb6m1o0z3
The randomized output of the md5 function is whatever is given between the parentheses.
The most significant property of hash encryption is that if the same hashing algorithm is applied, a certain input will always produce the same output. This is how they keep passwords secure:
On a website, a user opens an account. The password is hashed before being saved in the website's database.
When the user signs in again, the hash function is applied to the password they type.
From the previously saved password information, the website examines the database for an exact hash match.
The user is granted access once a match is identified.
A hacker's ability to reverse a hash function and acquire access to a user's password is practically impossible. In fact, even if it takes millions of attempts, it's quicker for them to guess the user's original password, demonstrating the need of creating strong, memorable passwords.
When and Why Were Passwords Invented?
Passwords aren't a brand-new notion. Sentries used them to challenge both friends and enemy approaching outposts all the way back in ancient Rome. Since then, they've appeared in countless espionage flicks and tree forts all around the world.
Digital computer passwords, on the other hand, were invented much earlier than you might think; even before the internet. The Compatible Time-Sharing System, a computerized operating system that provided researchers scheduled computer access, was developed by MIT in 1961. A computer scientist named Fernando Corbató suggested using passwords to protect each researcher's files. However, the early password systems' simplicity made them easy to hack, so cryptographer Robert Morris Sr. created the hashing approach, as stated above, a decade later.
Due to the pervasive threat of hacking that has existed since the dawn of the internet, new procedures have been introduced to password formation – such as the rules that define which characters must be used in a password.
What Are the Pros and Cons of Passwords?
Many people believe that passwords are the finest security measure available because they cover practically every single online account we have. In a nutshell, yes and no. Although passwords have some advantages over alternative techniques, they also have significant disadvantages.
Pro: Passwords are simple to make and remember. They're so simple to operate that even Granddad can do it!
Con: Hackers have gotten quite good at guessing simple passwords, especially the ones that are used frequently. Here's a list of the most popular passwords. If yours is on there, think about changing it right now!
Pro: They're adaptable. A password that you create will be simpler to remember than one that has been created for you. Con: In attempting to create a password that is easy to remember, many users make it too easy for hackers to guess.
Another huge flaw in password security has developed as a result of the numerous accounts we all use on a daily basis. Many users reuse the same password to remember how to check in to each website where they have an account. Unfortunately, a hacker only needs to guess or steal one account's password to have access to all of them.
How to Make a Strong Password You Can Remember
Everything on the internet is protected by passwords. Email, social networking, bank accounts, and more are all at risk. It's only natural to want your initial line of defense to be as effective as possible. Unfortunately, remembering a strong password isn't always easy, especially since you should use a different password for each account.
There are a few terrific techniques to establish strong, memorable passwords, thankfully (gym workouts and a protein shake not required).
Use a password manager
Make sure it's at least 12 characters long.
Use capital and lower-case letters, as well as numbers and symbols.
Use made-up terms instead of actual ones.
Substitutions that are evident should be avoided.
