![]() Various high-profile websites have attempted to block password managers, often backing down when publicly challenged. Please help update this article to reflect recent events or newly available information. This is known as a single point of failure. Or, as in the case of LastPass, the methods used to generate passwords may become comprimised, leading to passwords generated by the application being easier to guess.įurthermore, password managers have the disadvantage that any potential malicious individual or malware would just need to know one password to gain access to all of a user's passwords and that such managers have standardized locations and ways of storing passwords which can be exploited by malware. Generated passwords may be guessable if the password manager uses a weak method of randomly generating a "seed" that all passwords generated by this program. Some password managers may include a password generator. Some password managers attempt to use virtual keyboards to reduce this risk – though this is still vulnerable to key loggers that take the keystrokes and send what key was pressed to the person/people trying to access confidential information. A compromised master password renders all of the protected passwords vulnerable, meaning that a single point of entry can comprimise the confidentiality of sensitive information.Īs with password authentication techniques, key logging or acoustic cryptanalysis may be used to guess or copy the "master password". The security of this approach depends on the strength of the chosen password (which may be guessed through malware), and also that the passphrase itself is never stored locally where a malicious program or individual could read it. Some password managers require a user-selected master password or passphrase to form the key used to encrypt passwords stored for the application to read. Some applications store passwords as an unencrypted file, leaving the passwords easily accesible to malware or people attempted to steal personal information. Password managers may be installed on a computer or mobile device as an application or as a browser extension. Although, this is not required to use the application/browser extension. Password managers may choose to integrate multi-factor authentication through fingerprints, or through facial recognition software. Password managers typically require a user to create and remember one "master" password to unlock and access all information stored in the application. The main purpose of password managers is to alleveate a cyber-security phenomenon known as password fatigue, where an end-user can become overwhelmed from remembering multiple passwords for multiple services and which password is used for what service. Aside from passwords, these applications may also store data such as credit card information, addresses, and frequent flyer information. Ī password manager may assist in generating passwords, storing passwords, usually in an encrypted database. Password managers may exist as a mix of: computer applications, mobile applications, or as web browser extensions. Password managers can generate passwords and fill online forms.
