## Okta authentication for Lattice Sandboxes

The Lattice Sandboxes developer portal now uses Okta to manage access. The new sign-in experience replaces the previous email, password, and authenticator-app MFA flow with a passkey-based login at [https://login.developer.anduril.com](https://login.developer.anduril.com).

### What's new

* **Okta account activation**: New developers receive a welcome email from `no-reply@developer.anduril.com` with an **Activate Okta Account** link that expires seven days after it's sent.
* **Passkey-based MFA**: During activation, you register one of three passkey methods:
  * **Browser passkey**: Stored by your browser's password manager so that you can sign in from any device signed in to the same browser profile.
  * **Operating system biometrics**: Uses Touch ID, Face ID, Windows Hello, or another built-in platform authenticator bound to the current device.
  * **Physical FIDO or UBI key**: Uses a hardware token such as a YubiKey, which you can carry with you between devices.
* **New sign-in URL**: Sign in at [https://login.developer.anduril.com](https://login.developer.anduril.com). On success, Okta redirects you to the Lattice Sandboxes dashboard.
* **Self-service passkey management**: Manage your registered passkeys and password at [https://login.developer.anduril.com/account-settings/home](https://login.developer.anduril.com/account-settings/home). If you lose access to your passkey, email [lattice-developers@anduril.com](mailto:lattice-developers@anduril.com) for assistance.

> **Browser support**
>
> Use Chrome or a Chromium-based browser, such as Microsoft Edge or Brave, to access the Lattice Sandboxes developer portal. Firefox is not supported and will prevent you from completing the sign-in procedure.

For the full activation and sign-in procedures, see the [Sign in](/guides/developer-tools/sandboxes#sign-in) section of the Lattice Sandboxes guide.
