#加密安全须知

**Encryption Security Core Guidelines:**

1. **Strong Passwords are Fundamental:** Use long, complex, and unique passwords, and change them regularly. Avoid personal information.

2. **Enable Two-Factor Authentication (2FA):** Add a second layer of protection (such as a verification code or security key) for all important accounts.

3. **Update Systems and Software Promptly:** Patch security vulnerabilities to prevent exploitation.

4. **Be Cautious of Phishing Links and Attachments:** Do not click on links or download attachments from suspicious sources; beware of scams.

5. **Regularly Back Up Important Data:** Periodically back up encrypted critical data to offline or independent storage devices.

🔐 **Core: Strong Password + 2FA + Updates + Vigilance + Backup.**
