Systems that use passwords for authentication must have some way to check any password entered to gain access. If the valid passwords are simply stored in a system file or database, an attacker who gains sufficient access to the system will obtain all user passwords, giving the attacker access to all accounts on the attacked system and possibly other systems where users employ the same or ...
The easier a password is for the owner to remember generally means it will be easier for an attacker to guess. [12] However, passwords that are difficult to remember may also reduce the security of a system because (a) users might need to write down or electronically store the password, (b) users will need frequent password resets and (c) users are more likely to re-use the same password ...
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials> , where <credentials> is the Base64 encoding of ID ...
A password policy is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly. A password policy is often part of an organization's official regulations and may be taught as part of security awareness training. Either the password policy is merely advisory, or the computer ...
Bitwarden is an example of a password manager. A password manager is a software program to prevent password fatigue by automatically generating, autofilling and storing passwords. [1] [2] It can do this for local applications or web applications such as online shops or social media. [3] Web browsers tend to have a built-in password manager ...
Third-party (add-on) password management software such as KeePass and Password Safe can help mitigate the problem of password fatigue by storing passwords in a database encrypted with a single password. However, this presents problems similar to that of single sign-on in that losing the single password prevents access to all the other passwords ...
Password psychology is directly linked to memorization and the use of mnemonics. Mnemonic devices are often used as passwords but many choose to use simpler passwords. It has been shown that mnemonic devices and simple passwords are equally easy to remember and that the choice of convenience plays a key role in password creation. [8]
Passwords or passphrases created by humans are often short or predictable enough to allow password cracking, and key stretching is intended to make such attacks more difficult by complicating a basic step of trying a single password candidate. Key stretching also improves security in some real-world applications where the key length has been ...
