# Settings

> Manage your API keys, connected OAuth accounts, teacher model keys, HuggingFace integration, and notification preferences in Spectra settings.

Settings is organized into operational sections for your account, runtime credentials, and notifications.

## Profile and account

* choose **Light**, **Dark**, or **System** appearance
* review your user ID and connected avatar
* link or unlink **Google** and **GitHub** sign-in methods
* change your email or password
* open [Billing](/products/spectra/billing) or delete the account

## API keys

Create named Spectra API keys for runtime access. Keys start with `ax_`, and the full value is only shown when the key is created.

You can also verify or revoke saved keys from the same page.

## Teacher model keys (BYOK)

Save your own **OpenAI**, **Anthropic**, or **Google AI** keys when you want to use external teacher models during fine-tuning.

The built-in Axionic default teacher remains available without BYOK.

## Hugging Face token

Connect a personal Hugging Face token (`hf_...`) when you want trained models to live under your own Hugging Face account.

If you migrate existing hosted models into a personal account, Spectra shows the migration flow and warns about the temporary public exposure during transfer.

## Notifications

You can manage the email preferences currently exposed in the app:

* **Training completion**
* **Behavior alerts**
* **Usage warnings**
* **Product updates**

Account-security notifications stay enabled by default.
