Password generators, bug bounty programs, consistent third-party auditing and security scoring that shows repetitive or weak passwords are also included with both Bitwarden and LastPass. This means your master password is never sent to either company’s servers nor can it be accessed by a hacker. You’ll also find that both services utilize a “Zero-Knowledge” model. For instance, both companies use Advanced Encryption Standard (AES)-256 encryption and Password-Based Key Derivation Function 2 (PBKDF2) for ultra-tight security surrounding your password vault.

Bitwarden and LastPass both boast some of the best security and privacy features found with password managers.
