1) Never use your date of birth, license plate, home or cell phone number as your password. In literature, this is called a "social engineering attack ." It's the process of obtaining passwords solely from a person's information without using any scientific methods. Many users enter their landline phone number into their modem, and by reading the number on a shop's awning or billboard, they directly access the Wi-Fi network. Don't say, "Oh, what if they access my Wi-Fi unlimited?" You will be directly responsible for any hacking attempts or statements made online on behalf of an illegal organization using your Wi

-Fi network. 2) Especially don't use the same password you use for email elsewhere. For example, the password for Facebook and Twitter accounts is usually the same as your email address. You'll be wondering, "What's the big deal?" Develop your own method. For example, at least start your Facebook login with "Fb," start your email with "Em," and start your Twitter login with "Tw."

3) In case your computer has a keylogger (spyware that records keyboard movements), be sure to use a virtual keyboard. Just like when logging into banking systems. If the system doesn't have a virtual keyboard, you can open the on-screen keyboard in Windows by going to Windows Start - Accessories - Ease of Access - On-Screen Keyboard. You can't prevent malicious programs like keyloggers from entering your computer. They can infiltrate your computer from many places, including a flash drive. Use a licensed antivirus to prevent this.

4) Don't use sequential numbers when creating passwords. Be sure to use at least one lowercase letter, one uppercase letter, a number, and a symbol ($, #, +, ., %, &, ?, =). Passwords must be at least 8 characters long; shorter passwords, such as 2-3 characters, are very easy to detect. You can read the SplashData news article about commonly used passwords at the link below.

5) Don't rewrite your passwords just because you forget them. You risk being exposed to unwanted people seeing your password. So, what should we do? Let's say you have four debit cards. How can you remember each one with a different PIN? It's very easy. The card must have a 12-16 digit number on it. You can use the first two digits, the last two digits, or any four digits of your choosing as your PIN. Use the same method for all cards; the PINs will be different.


Speaking of credit cards, your credit card information is sufficient for online shopping; you don't need a credit card. Your CV2 number, expiration date, and credit card number will do. Never give your credit card to a waiter or gas station employee and ask them to withdraw money. Go to the POS machine yourself; a malicious person might photograph your credit card on the way. Constantly check your credit card charges at the ATM and ask the bank about any charges you don't understand.
6) It's very easy for a wireless network to be tapped and for emails and messages to be intercepted. Don't send your credit card information via a messaging program or email. Even sending an SMS is safer; be sure to delete it immediately after sending it. By the way, if you keep your passwords on your mobile phone, be careful; forgetting to leave your phone somewhere puts you at risk. 7) Documents containing a company's top-secret information or government security information should not be stored in folders without encryption. Invisible folders and invisible drives in Windows can be created by various programs. Just don't forget to delete these folders and drives when formatting your computer. 8) Don't rely on Windows login passwords; the initial login passwords in Windows 7 and 8 are easily cracked. If you must use Windows, encrypt folders and drives. To prevent anyone from messing with your computer when you're on lunch break or going to the bathroom at work, you can lock your screen by pressing CTRL+ALT+DEL and selecting the Lock Computer option on the screen that appears. 9) Never leave your device passwords at their factory settings. For example, cameras and modems come with a factory password; be sure to change it. Otherwise, others will be able to monitor your home or workplace while you're monitoring it online, and others will use your modem. 10) If you're a software developer, don't save user passwords directly to the database. Use message hashing algorithms like MD6 or SHA1 to save them. This way, even if the database is compromised, user passwords cannot be learned. It may be necessary to encrypt fields other than the password in a table. Use encryption algorithms like AES and RC6 for these .
