public static MongoCredential createCredential(String userName,
                                               String database,
                                               char[] password)
```
    Creates a MongoCredential instance with an unspecified mechanism. The client will negotiate the best mechanism based on the version of the server that the client is authenticating to. If the server version is 3.0 or higher, the driver will authenticate using the SCRAM-SHA-1 mechanism. Otherwise, the driver will authenticate using the MONGODB_CR mechanism.
    
    Parameters:
    
    userName - the user name
    
    database - the database where the user is defined
    
    password - the user's password
    
    Returns:

```
    Creates a MongoCredential instance for the SCRAM-SHA-1 SASL mechanism. Use this method only if you want to ensure that the driver uses the SCRAM-SHA-1 mechanism regardless of whether the server you are connecting to supports the authentication mechanism. Otherwise use the createCredential(String, String, char[]) method to allow the driver to negotiate the best mechanism based on the server version.
    
    Parameters:
    
    userName - the non-null user name
    
    source - the source where the user is defined.
    
    password - the non-null user password

    Creates a MongoCredential instance for the MongoDB Challenge Response protocol. Use this method only if you want to ensure that the driver uses the MONGODB_CR mechanism regardless of whether the server you are connecting to supports a more secure authentication mechanism. Otherwise use the createCredential(String, String, char[]) method to allow the driver to negotiate the best mechanism based on the server version.

  - createGSSAPICredential
```
public static MongoCredential createGSSAPICredential(String userName)
```
    Creates a MongoCredential instance for the GSSAPI SASL mechanism.
    To override the default service name of "mongodb", add a mechanism property with the name "SERVICE_NAME".
    To force canonicalization of the host name prior to authentication, add a mechanism property with the name "CANONICALIZE_HOST_NAME" with the valuetrue.
    To override the Subject with which the authentication executes, add a mechanism property with the name "JAVA_SUBJECT" with the value of a Subject instance.
    To override the properties of the SaslClient with which the authentication executes, add a mechanism property with the name "JAVA_SASL_CLIENT_PROPERTIES" with the value of a Map<String, Object instance containing the necessary properties. This can be useful if the application is customizing the default SaslClientFactory.
    
    Parameters:
    
    userName - the non-null user name
    
    Returns:
    
    the credential
