- Updated the GenerateMachineID function to generate a machine ID with the prefix "auth0|user_". - The random part of the ID is now 25 bytes, producing a 50-character hexadecimal string. - This change improves the uniqueness and format of generated machine IDs, aligning with authentication standards.
