How to set strong passwords for 138 Enterprise Email accounts?

To set strong passwords for 138 Enterprise Email, use a combination of uppercase letters, lowercase letters, numbers, and special characters, with a minimum length of 12 characters. Avoid common words, personal information, or sequential patterns. This aligns with 138's security baseline requirements for mitigating unauthorized access risks. Note that weak passwords may trigger system restrictions or temporary locks after consecutive failed attempts. For high-risk accounts (e.g., administrators, financial roles), enable available two-factor authentication if supported. After setup, verify login via web, mobile, or PC clients. If issues persist, contact 138's official support for password resets or security reviews, as custom configurations may vary by domain or subscription plan.
For enhanced security, consider using client-specific passwords for third-party applications and restrict protocol permissions as part of 138's security baseline.
