Standard authentication using a MySQL username and password, such as caching_sha2_password.

The Kerberos authentication protocol for passwordless authentication. For more information about Kerberos authentication, see Kerberos Pluggable Authentication.

Support added in Connector/ODBC 8.0.26 for Linux clients, and 8.0.27 for Windows clients.

Multi-Factor Authentication (MFA) by utilizing the PASSWORD1 (alias of PASSWORD), PASSWORD2, and PASSWORD3 connection options. In addition there are PWD1, PWD2, and PWD3 aliases.

Support added in Connector/ODBC 8.0.28.

FIDO-based authentication is supported and Connector/ODBC supports the FIDO-based WebAuthn Pluggable Authentication plugin. See the general WebAuthn Pluggable Authentication documentation for installation requirements and implementation details.

A callback usage example:

// SQL_DRIVER_CONNECT_ATTR_BASE is not defined in all driver managers.
// Therefore use a custom constant until it becomes a standard.
#define MYSQL_DRIVER_CONNECT_ATTR_BASE 0x00004000

// Custom constants used for callback
#define CB_FIDO_GLOBAL MYSQL_DRIVER_CONNECT_ATTR_BASE + 0x00001000
#define CB_FIDO_CONNECTION MYSQL_DRIVER_CONNECT_ATTR_BASE + 0x00001001

// Usage example
// Callback function inside code:
void user_callback(const char* msg)
{
   // Do something ...
}
SQLHENV henv = nullptr;
SQLAllocHandle(SQL_HANDLE_ENV, nullptr, &henv);

// Set the ODBC version to 3.80 otherwise the custom constants don't work
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION,                               
(SQLPOINTER)SQL_OV_ODBC3_80, 0);

SQLHDBC hdbc = nullptr;
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc);

// CB_FIDO_X is either CB_FIDO_GLOBAL or CB_FIDO_CONNECTION
SQLSetConnectAttr(hdbc, CB_FIDO_X, &user_callback, SQL_IS_POINTER);

SQLDriverConnect(hdbc, hwnd, conn_str, ....);
