Advice Request Understanding how Bitwarden Send works

[Ink]

Similar to all of your Bitwarden Vault data, everything shared through Bitwarden Send is end-to-end encrypted. This means that Bitwarden cannot see the contents of your Send, whether that be a text snippet or a file.

One of the important components of Bitwarden Send feature is built-in automatic deletion. Because the sensitive data will be deleted, users can ensure their information does not linger, or remain in a system over which they have no control. For example, in a typical sharing model, once a piece of information is emailed or messaged, it stays in those systems often forever. Using the Bitwarden end-to-end security model, while the Send link may remain, it will no longer work, and the data attached to that Send will not stick around.
