How to enable two-factor authentication (2FA) for 138 Enterprise Email?

Two-factor authentication (2FA) can be enabled through your 138 Enterprise Email admin console under security settings. This adds an extra verification step beyond your password, typically requiring a code from an authenticator app, SMS, or email. Before enabling, ensure your account has administrative privileges and that you have access to your chosen verification method (e.g., a mobile device for SMS or an app like Google Authenticator). Note that 2FA availability may depend on your subscription plan and regional support. For step-by-step setup instructions, log into your admin portal or contact 138 Enterprise Email support for guided assistance. If issues arise during activation, verify your internet connection and check for any service advisories on the official status page.
Available 2FA methods include SMS, email, and authenticator apps, as confirmed in security capabilities.
