# CdpTokenGenerator

> Unified token generator for CDP authentication.

Package: [`com.coinbase.cdp.auth`](/sdks/cdp-sdks-v2/java/com/coinbase/cdp/auth/index)

```java theme={null}
public class CdpTokenGenerator extends Object
```

Unified token generator for CDP authentication.

Generates bearer tokens and optionally wallet auth tokens in a single call. This class composes the existing [`JwtGenerator`](/sdks/cdp-sdks-v2/java/com/coinbase/cdp/auth/JwtGenerator "class in com.coinbase.cdp.auth") and [`WalletJwtGenerator`](/sdks/cdp-sdks-v2/java/com/coinbase/cdp/auth/WalletJwtGenerator "class in com.coinbase.cdp.auth") to provide a simplified, unified API.

Example usage:

```

 // With wallet secret for write operations
 CdpTokenGenerator generator = new CdpTokenGenerator(
     "api-key-id", "api-key-secret", Optional.of("wallet-secret"));

 CdpTokenRequest request = CdpTokenRequest.builder()
     .requestMethod("POST")
     .requestPath("/v2/evm/accounts")
     .includeWalletAuthToken(true)
     .requestBody(Map.of("name", "my-account"))
     .build();

 CdpTokenResponse tokens = generator.generateTokens(request);
 // tokens.bearerToken() - for Authorization header
 // tokens.walletAuthToken() - for X-Wallet-Auth header
 
```
