A password is generally a secret word or string used to access a computer or internet service. Passwords are used to authenticate a user's identity and are typically entered alongside a username. For security purposes, passwords are usually composed of complex characters and changed regularly. Proper storage and strength of passwords are crucial for the security of computer systems and personal accounts. The first computer password was used in the 1960s at MIT on a time-sharing operating system called the Compatible Time-Sharing System (CTSS). This password was '1234'. However, this password does not meet modern security standards and is not considered secure by today's measures. With advances in computer security, encryption techniques and security protocols have significantly improved, and encryption standards have become more complex and secure.

In password guessing, human psychology and behaviors are also considered. Initially, information like phone numbers, bank account numbers, popular words, email addresses, and home addresses are tested. For someone attempting to crack a password, it doesn't matter who owns the account; accessing the system is sufficient. Therefore, complex passwords are used and frequently changed, especially in workplaces. Additional measures like one-time password generators are also commonly used to enhance password security.

Some key points for creating a secure password include:

• Length: Passwords should be at least 8 characters long. The most secure ones are 14 characters or more.
• Avoid meaningful words: Avoid using logical or meaningful words in your password. For example, specific words in your password can make it easier to guess.
• Use different character types: Create a strong password by combining different character types (letters, numbers, and special characters). This variety makes it significantly harder to guess.
• Choose memorable but hard-to-guess passwords: Selecting a password requires a delicate balance between memorability and security. A password that can be easily remembered facilitates its use in daily life, but it is also important to make it difficult for others to guess. Choosing a complex yet memorable word, phrase, or sentence is an effective way to achieve this balance. This type of password enhances security while reducing the risk of forgetting, improving the user experience.
• Reduce the risk of dictionary attacks: Avoid words that can be easily found by computers, such as common words or phrases that might be included in extensive dictionary scans.
• Avoid personal information: Refrain from using personal information in your passwords, such as movie titles, famous quotes, or birth dates. Such information can be easily guessed or found.
• Use unique passwords on different platforms: Using different passwords across various platforms increases your security. Using the same password in multiple places can bring risks.
