✓Everything runs locally in your browser — your input is never uploaded to a server, so it is safe for private or sensitive data.
✓Use a password manager to generate and store unique credentials per site.
✓Classic ciphers (Caesar, ROT) are for learning, not real protection.
✓Enable multi-factor authentication wherever it is offered.
✓Never test a real production password in any online tool — use a representative sample.
