+Bitwarden uses [PBKDF2](https://bitwarden.com/help/kdf-algorithms/#pbkdf2) as its key derivation function (KDF) algorithm by default. It also offers [Argon2](https://bitwarden.com/help/kdf-algorithms/#argon2id), which is more secure, as an alternative. You can change your account's KDF algorithm in the web vault.

 Bitwarden also features [Bitwarden Send](https://bitwarden.com/products/send), which allows you to share text and files securely with [end-to-end encryption](https://bitwarden.com/help/send-encryption). A [password](https://bitwarden.com/help/send-privacy/#send-passwords) can be required along with the send link. Bitwarden Send also features [automatic deletion](https://bitwarden.com/help/send-lifespan).
 
 You need the [Premium Plan](https://bitwarden.com/help/about-bitwarden-plans/#compare-personal-plans) to be able to share files. The free plan only allows text sharing.
