Paperzilla supports both anonymous onboarding and email-based account access.

## Anonymous start

You can begin project setup in chat on [paperzilla.ai](https://paperzilla.ai) before creating a full account.

When you save delivery, Paperzilla asks for email and sends a magic link to complete access.

## Magic-link sign in

Paperzilla uses one-time email links/codes for authentication.

Typical flow:

1. Enter your email.
2. Open the email from Paperzilla.
3. Click link or enter code.
4. Continue where you left off.

## Existing account handoff

If you enter an email that already has a Paperzilla account during setup, Paperzilla sends a sign-in link and restores your setup after sign in.

## Access boundaries

* Project onboarding can start anonymously.
* Full project dashboard and management require account access.
* Private project links require owner access.

## Profile completion

If needed, Paperzilla asks for missing profile fields (for example first name) before continuing.
