Welcome to **The Nest**! This guide serves as your starting point for creating your account, navigating available services, and getting support whenever you need it.
* **A Username:** Choose carefully! Usernames cannot be easily changed once created.
* **A Working Email Address:** Email aliases are completely fine. This address will be used for your initial setup, account recovery, and optional service notifications.
The Nest uses **passwordless authentication** (powered by Keycloak and WebAuthn). Instead of remembering complex passwords, you'll log in securely using a **passkey**.
> A passkey lets you sign in using your physical device or password manager instead of typing a password. You will use the exact same passkey for all services across The Nest.
*Additional services require separate administrator authorization. Please review the [Requesting Service Access](access-requests.md) guide for more information.*
As you explore the user guides for each platform, signing in is straightforward. Most services use a single button labeled **"Sign in with The Nest"**.
> Depending on the app, you might see phrases like *"Sign in with OIDC"*, *"Sign in with Keycloak"*, or *"Sign in with SSO"*. These all mean the exact same thing: sign in using your standard Nest passkey!
If you run into any issues along the way, here is how to resolve them:
* **Unable to Sign In?** Try using a different passkey-supported device, or reach out to an administrator on Matrix.
* **Service Unavailable or Unresponsive?** Systems undergo automated daily updates around **03:00 EST**. Please wait a few minutes and refresh your browser.
* **Need General Assistance?** Head over to the **Admin** space in Matrix and drop your question in the **"Ask an Admin"** room.
