Keeper (password manager)
Keeper is a password manager application and digital vault created by Keeper Security that stores website passwords, financial information and other sensitive documents using 256-bit AES encryption, zero-knowledge architecture and two-factor authentication.

In 2018, Keeper was named "Best Password Manager" by PC Mag and nominated Editors' Choice with an "Excellent" rating. Keeper was rated "Best Security" by Tom's Guide.

Features 
Files and passwords in Keeper can be synced, backed up in the cloud, encrypted with a 256-bit AES key derived from the user's master password using PBKDF2.  Every record in the user's private vault is encrypted and stored with a unique encryption key.  Keeper also addresses the problem of password fatigue, by autofilling login and password fields with stored information. Sharing passwords between Keeper users is performed using 2048-bit RSA encryption.

A feature called "Keeper DNA" provides multi-factor authentication using connected devices, such as a smartwatch, to verify a user's identity when logging into the vault.

BreachWatch is a feature that monitors the dark web for stolen passwords and notifies the user within their vault.

KeeperChat, a secure communications platform was launched in March 2018 that provides encrypted messaging, self-destructing messages, retraction and two-factor authentication.

Keeper is a free service for storing passwords on a single device and has an optional annual subscription with cross-device syncing.

Keeper comes pre-loaded on the Orange Dive 70 smartphone, Samsung phones, América Móvil phones and most AT&T Android phones.  As of January 2015, Keeper has more than 9 million registered users and works with over 3,000 companies.  Keeper is available for download on Android, iOS, Windows, Mac, Windows Phone, Linux, Kindle, and Nook, and available as a browser extension for IE, Chrome, Firefox, Safari and Opera. Keeper is also available for Microsoft Edge.

Keeper for Business and Enterprise Use 
Keeper Enterprise is a multi-tenant password management and secure file storage platform for businesses. Features include file sharing, user provisioning, auditing, reporting, Active Directory integration and delegated administration, all of which are available within a centralized admin console. In June 2019 Keeper launched BreachWatch for business customers, a service which searches the Dark Web for login credentials exposed through a public breach and prevents credential stuffing or account takeover attacks.

History 
Keeper Security was founded in 2009 by Darren Guccione and Craig Lurey while on a business trip to China.  As of May 15, 2019 the company  has 145 employees in Chicago, Northern California and Cork, Ireland.

Incidents 
In December 2017, Keeper was bundled with Windows 10 by Microsoft. Google security researcher Tavis Ormandy disclosed that the software recommended installing a browser addon which contained a vulnerability allowing any website to steal any password. A nearly identical vulnerability was already previously discovered and disclosed to Keeper in 2016. Within 24 hours the company issued a patch. Days later, the company that makes Keeper sued Ars Technica claiming their article was defamatory and misleading. The lawsuit was dismissed on March 30, 2018 and Ars Technica added further clarifications to the article.  Keeper launched a public vulnerability disclosure program with Bugcrowd following the lawsuit.
