Settings

The Settings page lets you manage your account, security credentials, and preferences.

Profile

Edit your personal information:

• Full name — Your display name
• Email address — Changing your email triggers a verification flow: a confirmation email is sent to the new address, and the change only takes effect after you click the verification link

Click Save to apply changes. The button is disabled until you modify a field.

Security & Authentication

Manage your passkeys (WebAuthn credentials) — the cryptographic keys used to log in to Castmill.

Viewing Passkeys

A list of all registered passkeys is shown, each displaying:

• Name — A label you can customize (e.g., "MacBook Pro", "iPhone")
• Date added — When the passkey was registered

Adding a Passkey

1. Click Add New Passkey
2. Your browser or device prompts you to create a new credential (fingerprint, Face ID, security key, etc.)
3. Enter a name for the passkey
4. The passkey is registered and can be used to log in from that device

tip

Register passkeys on multiple devices to ensure you can always access your account. If you lose access to all devices with registered passkeys, you will need to use the credential recovery flow.

Managing Passkeys

• Rename — Click the edit button to change a passkey's display name
• Remove — Click the delete button to remove a passkey

caution

You cannot remove your last remaining passkey. At least one passkey must always be registered to maintain account access.

Onboarding Tour

If you want to revisit the guided walkthrough that appears for new users:

1. Click Reset Tour
2. Confirm in the dialog
3. The onboarding tour restarts on your next page load

Account Management

Danger Zone

These actions are irreversible.

Delete Account

1. Click Delete Account
2. Read the warning about data loss and passkey cleanup
3. Confirm deletion

Important considerations:

• All your data, credentials, and organization memberships are permanently removed
• If you are the sole administrator of an organization, deletion is blocked — you must first transfer admin rights or delete the organization
• The system attempts to clean up passkeys from your devices using the browser's credential management API
