Open the vault
Everyone sharing this vault types the same passphrase.
The passphrase never leaves this browser. It unwraps the entries here — the copy in the cloud is scrambled, and nobody, this site included, can read it without the passphrase. Lose the passphrase and the entries are gone with it.
