Secure Your MailCub Account with Two-Factor Authentication

This page explains how to secure your MailCub account by enabling two-factor authentication using an authenticator app or email-based OTP

Secure Your Account

MailCub takes security and data protection seriously. Every user account is protected with a login password, and you have the option to enable Two-Factor Authentication (2FA) for an extra layer of protection. You can choose between:

  • Authenticator app-based OTP (e.g., Google Authenticator, Microsoft)
  • Email-based OTP (sent to your email each login)

How to Enable 2FA

    1. Log into your MailCub account.
    2. Navigate to: Profile → Settings → Manage Security.

  • Whenever possible, prefer authenticator app-based 2FA (it's more secure than email OTP).
  • Periodically review your Security settings and update them if needed.
