Bitwarden offers users two locations to store their passwords. Storing passwords on Bitwarden’s servers allows for simple cloud-sync between all devices, and Bitwarden protects user passwords with 256-bit AES encryption and a secure SRP handshake.
For users with strong network security, Bitwarden also offers the option for local data storage. You can keep your data within your network, which eliminates the (extremely low) risk of a man-in-the-middle attack. Bitwarden is one of the only free password managers that offers local data storage.
