It is common for computer users to reuse the same password on multiple websites. This poses a significant security risk because an attacker only needs to compromise one website to access other websites used by the victim. This issue is exacerbated by reuse of user names and Web sites that require e-mail logins, because it is easier for an attacker to track a single user across multiple Web sites. Password reuse can be avoided or minimized by using mnemonic techniques, writing down passwords on paper, or using a password manager. [44] In The Memorability and Security of Passwords,[16] Jeff Yan et al. examine the effect of user advice on good password choice. They found that passwords based on thinking about a sentence and the first letter of each word are just as memorable as naively chosen passwords and are just as difficult to crack as randomly generated passwords. allow, biometrics, computer shortcuts, default password, login, OTP, password, password, password generator, password manager, password protection, picture password, PIN, reset password, security conditions, username 3. DON`T SHARE YOUR PASSWORD – Your password is only as valuable as the information it protects.

Typically, a system should provide a way to change a password, either because a user believes the current password has been (or could be) compromised, or as a precautionary measure. If a new password is transmitted to the unencrypted system, security can be lost (e.g., by eavesdropping) even before the new password can be installed in the password database, and if the new password is passed on to a compromised employee, little gain is achieved. Some websites include the user-selected password in an unencrypted confirmation email, with the vulnerability obviously high. In this attack method, passwords (electronic or paper) are observed as they are entered. Enterprise Password Manager / Privileged Password Manager are a special subset of password managers used to manage privileged enterprise account credentials (root, administrator, etc.). The computer password is used to distinguish and authenticate a user if the user has the correct secret key or password to access the computer system or network, and if users do not come with the correct password, it denies the user access to the computer system or network. Advanced password-authenticated key agreement systems (e.g., AMP, B-SPEKE, PAK-Z, SRP-6) avoid both conflict and limitation of hash-based methods. An advanced system allows a client to prove knowledge of the password to a server where the server only knows a hashed password (not exactly) and where the unhashed password is required to access it. A password, sometimes called a passcode (e.g., for Apple devices),[1] is secret data, usually a string of characters typically used to confirm a user`s identity.

[1] Traditionally, passwords were expected to be remembered,[2] but the large number of password-protected services that a typical person accesses can make remembering unique passwords impractical for each service. [3] Using the terminology of the NIST Digital Identity Guidelines,[4] secrecy is held by a party called the requester, while the party verifying the identity of the requester is called the verifier. If the applicant successfully proves knowledge of the password to the verifier using an established authentication protocol[5], the verifier may infer the identity of the applicant. An alternative to limiting the speed at which an attacker can guess a password is to limit the total number of guesses that can be made. The password can be disabled after a small number of consecutive bad assumptions (e.g. 5), which requires a reset. And the user may be prompted to change the password after a larger cumulative number of bad guesses (e.g., 30) to prevent an attacker from making an arbitrarily high number of bad assumptions by interspersing them between the correct assumptions of the legitimate password holder. [25] Conversely, attackers can use the knowledge of this mitigation to perform a denial of service attack against the user by intentionally locking the user out of their own device; This denial of service can open up further opportunities for the attacker to manipulate the situation to their advantage through social engineering.

Therefore, it is highly recommended that you secure your BIOS setup with a strong password. Sometimes abbreviated to PW and PWD, a password is a series of secret characters or words used to authenticate and secure access to a digital system. Adding passwords ensures that only people with the right to view or access computers or data can access them. Now, let`s talk about BIOS or CMOS password, this computer utility has all the functions and almost all the system configuration information stored in it and imagine when it goes to someone who has access, can modify sensitive information and possibly corrupt your boot process and any other parameter that is important for the proper functioning of the computer. Most passwords consist of multiple characters, which can usually contain letters, numbers, and most symbols, but no spaces. While it`s good to choose a password that`s easy to remember, you shouldn`t make it as easy as others might guess. The most secure passwords use a combination of letters and numbers and do not contain real words. By implementing best practices for passwords, such as Through an automated tool, these attacks can be largely repelled or repulsed. The following six password security tips come from the U.S. National Counterintelligence and Security Center (NCSC): Other authentication methods can also be combined with or instead of passwords. These options are: Passwords are vulnerable to interception (i.e. „spying”) when transmitted to the computer or authenticating person.

If the password is transmitted as electrical signals over unsecured physical cabling between the user access point and the central system that controls the password database, it is subject to spying by eavesdropping methods. When transmitted over the Internet as aggregated data, anyone who can observe packets with credentials can spy on the detection with a very low probability of detection. Trying to crack passwords by trying as many ways as time and money allow is a brute force attack. A related method that is slightly more effective in most cases is a dictionary attack. In a dictionary attack, all words in one or more dictionaries are tested. Common password lists are usually also tested. Web passwords: The web password is used when you work online, for example before using an email program, you must first register on the website or app to provide them with your credentials such as name, surname, desired username, and password. Generate password rates based on dictionary words of any language. Password managers are software applications that apply best practices for generating and securing passwords (for example, through encryption). Using a master password/key, the user can instruct the password manager to automatically extract the correct password from a database and authenticate with a system/software by filling out a form.
