Bitwarden offers encryption on a zero-knowledge model — meaning only you have access to your passwords — using the cipher AES-256, which protects passwords using hundreds of thousands of rounds of password “hashing” that turns your passwords into scrambled versions of themselves that can’t be reverse-engineered. It gives you the option of hosting your passwords on Bitwarden’s servers or locally, eliminating any risk of a data breach on the company’s end.
Bitwarden makes it easy for you to create, store, and access your passwords. Bitwarden stores all of your logins in an encrypted vault that syncs across all of your devices. Since it's fully encrypted before it ever leaves your device, only you have access to your data. Not even the team at Bitwarden can read your data, even if we wanted to. What is Bitwarden? Password solution that supports end-to-end encryption, cross-platform applications, password generator, vault health reports and more. Bitwarden is 100% open source software. The source code for Bitwarden is hosted on GitHub and everyone is free to review, audit, and contribute to the Bitwarden codebase.

The potential downside of zero-knowledge security and encryption is that, if you ever lose your password, it’s gone for good. But the overall upsides of Bitwarden’s approach are considerable: If you pair strong passwords with the deep password-hashing functionality the software provides, you should have plenty of peace of mind on the security front.
