Everything in your vault, including your passwords, verification codes, notes, IDs, cards, bank accounts and attachments, is end-to-end encrypted on your device before it's synced. Only you hold the keys, so only you can read it. Security model

What we collect

Only your account ID, which we use to sign you in and sync your vault across your devices.
