What is the difference between end-to-end encryption and password protection?

If you set a password on your wall, we require the user to provide that password to access the photos. You can change or remove the password at any time. If you enable End-to-end-encryption, you add another layer of cryptographic security on top of the encryption we already apply for transport and storage in LiveWall. If you lose the passphrase for E2EE, your photos will be unrecoverable. Use E2EE for truly sensitive data, and password protected walls for everyday use.
