# Authentication

> Public API authentication and login scope.

Public APIs use a MyRouter API key.

```http theme={null}
Authorization: Bearer <api_key>
```

Anthropic-compatible migration headers are accepted where the platform contract defines them, but Bearer authentication is the canonical MyRouter public pattern.

V0 self-serve login is product-owned and limited to:

* Google login.
* GitHub login.

Provider OAuth/OIDC start and callback routes are framework-owned implementation details. The stable internal product-control API models session/user context and logout, not provider callback mechanics.
