Security Notes

• Randomness is provided by QRandomGenerator, backed by the operating system’s cryptographically secure random source.
• Password generation guarantees that each selected character group contributes at least one character.
• The final password is shuffled to avoid structural patterns.
• All password generation happens locally on your machine.
