Bitwarden
Bitwarden is a free and open-source password management service that stores sensitive information such as website credentials in an encrypted vault. The Bitwarden platform offers a variety of client applications including a web interface, desktop applications, browser extensions, mobile apps, and a command-line interface. Bitwarden offers a cloud-hosted service as well as the ability to deploy the solution on-premises.

History
Bitwarden debuted in August 2016 with an initial release of mobile applications for iOS and Android, browser extensions for Chrome and Opera, and a web vault. The browser extension for Firefox was later launched in February 2017. In February 2017, the Brave web browser began including the Bitwarden extension as an optional replacement password manager. In January 2018, the Bitwarden browser extension was adapted to and released for Apple's Safari browser through the Safari Extensions Gallery.

In February 2018, Bitwarden debuted as a stand-alone desktop application for macOS, Linux, and Windows. It was built as a web app variant of the browser extension and delivered on top of Electron. The Windows app was released alongside the Bitwarden extension for Microsoft Edge in the Microsoft Store a month later.

In March 2018, Bitwarden's web vault was criticized for embedding unconstrained third-party JavaScript from BootstrapCDN, Braintree, Google, and Stripe. These embedded scripts could pose as an attack vector to gain unauthorized access to Bitwarden users' passwords. These third-party scripts were removed as part of the Bitwarden 2.0 Web Vault update, released in July 2018.

In May 2018, Bitwarden released a command-line application enabling users to write scripted applications using data from their Bitwarden vaults. In June 2018, Cliqz performed a privacy and security review of the Bitwarden for Firefox browser extension and concluded that it would not negatively impact their users. Following the review, Bitwarden was made available as an optional password manager in the Cliqz web browser.

In October 2018, Bitwarden completed a security assessment, code audit, and cryptographic analysis from third-party security auditing firm Cure53.

In June 2020, Bitwarden completed another security audit from security firm Insight Risk Consulting to evaluate the security of the Bitwarden network perimeter as well as penetration testing and vulnerability assessments against Bitwarden web services and applications. In August 2020, Bitwarden achieved SOC 2 Type 2 and SOC 3 certification.

In December 2020, Bitwarden announced that it was HIPAA and Privacy Shield compliant.

Reception 
In January 2021, in its first password-protection program comparison, U.S. News & World Report selected Bitwarden as "Best Password Manager". In February, with competitor LastPass about to drop a feature in its free version, CNET recommended Bitwarden as best free app for password synchronization across multiple devices, while Lifehacker recommended it as "the best password manager for most people."

Critics have praised the features offered in the software's free version, and the low price of the premium tier compared to other managers. The product was named the best "budget pick" in a Wirecutter password manager comparison. Bitwarden's secure open source implementation was also praised by reviewers. However, the software was criticized for its lack of additional features, and some reviewers noted its basic and less intuitive interface compared to other password managers.
