Local encryption basics for account collectors

What “encrypted on this device” means in practice, when cloud sync helps, and how PIN unlock fits the model.

“Encrypted on this device” means your vault is encrypted with AES-256-GCM before it is saved, so the readable vault never sits in plain localStorage. A PIN-derived key unlocks it in the browser.

Every vault, free or paid, is saved to your account in that encrypted form so it can sync. Be realistic about a 4-digit PIN: we store a check value made from your username and PIN to sign you in, and someone with our database could guess a PIN that short.

Export a backup before you change devices. Import restores the encrypted package; you unlock with the same PIN you used when you exported.

If you forget the PIN, we do not reset it. That is the tradeoff of a vault that cannot be reset by a support inbox.

Google convenience mode is a different contract: we store a vault key and release it only to your authenticated Google session on this site. Neither mode is zero-knowledge. Privacy and Security use that wording on purpose.

The 2FA codes and quick notes tabs are different again: they are saved only on this device, without encryption, and are not part of the vault or its backup.

This is not a SOC 2, ISO, or insurance page. Those claims are not published here. If that changes, link a real report — not a placeholder badge.

Questions people ask

Can LoginScout reset a forgotten PIN?
No. There is no PIN-reset email. Export a backup while you still remember the PIN.
Is Google sign-in zero-knowledge?
No. Google convenience mode stores a vault key for that Google session. PIN vaults are not zero-knowledge either, because a 4-digit PIN is short. Security and Privacy have the exact wording.
Do you publish SOC 2 or ISO badges?
Not on this site. Do not invent certifications. If an audit report is published later, the security page should link the real document.

Create a free vault and keep logins, mail, and MFA together.
