It is never stored on any server, transmitted across any network, or written in plaintext to persistent browser storage. Changing or rotating a master password is fundamentally different from resetting a traditional web account password: it requires decrypting all existing records locally in browser memory and re-encrypting the entire vault under an entirely new symmetric key.
