A password manager is a computer program that allows users to store and manage their passwords for local applications or online services such as web applications, online shops or social media. A web browser generally has a built in version of a password manager. These have been criticised frequently as many have stored the passwords in plaintext, allowing hacking attempts.
Password managers can generate passwords and fill online forms. Password managers may exist as a mix of: computer applications, mobile applications, or as web browser extensions.
A password manager may assist in generating passwords, storing passwords, usually in an encrypted database. Aside from passwords, these applications may also store data such as credit card information, addresses, and frequent flyer information.
The main purpose of password managers is to alleviate 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.
Password managers typically require a user to create and remember one "master" password to unlock and access all information stored in the application. Password managers may choose to integrate multi-factor authentication through fingerprints, or through facial recognition software. Although, this is not required to use the application/browser extension.
