# TigerTokenAuthProvider

- Package: [@gooddata/sdk-backend-tiger](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-backend-tiger/index.md)
- Kind: class
- Source: https://github.com/gooddata/gooddata-ui-sdk/blob/rel/11.64/libs/sdk-backend-tiger/src/auth.ts

This implementation of authentication provider uses an API Token as bearer of authentication.

**Signature:**

```typescript
export declare class TigerTokenAuthProvider extends TigerAuthProviderBase 
```
**Extends:** [TigerAuthProviderBase](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-backend-tiger/sdk-backend-tiger.tigerauthproviderbase/index.md)

## Remarks

You can provide token at construction time and it will be passed on all calls to Tiger APIs

This is a go-to authentication provider for command-line applications. While nothing stops you from using this provider in UI applications, keep in mind that this is discouraged due to security holes it leads to; having the token hardcoded in a UI application means anyone can find it and use it for themselves.
