# SAM Crypto Token Properties

SAMCryptoToken implements the SAM and requires access to QSCD. Once configured, it can be used to create remote signatures on behalf of the users. 

SAMCryptoToken can be attached to any Signer implementation. SAMCryptoToken can be operated in 2 modes:

1. **Signing-only mode:** To support only remote signing operations (the user and key management is handled by different component in the solution)
2. **Key Management mode:** To support signing, user, and key management operations (in this case, it is a single point of SAM key management)
3. **User Management mode:** To support additional user management functions, such as create user, configure authorization, or remove user.
