Two-step authentication (2FA)
Two-factor authentication (2FA) significantly increases your account's security. It works by requiring an additional, one-time code during login, on top of your standard password.
Good to know: On every new MessageFlow account, the 2FA feature is active by default with SMS verification. This guide shows you how to manage its settings.
How to Configure 2FA?
Choose Your Verification Channel
The system allows for a flexible choice of channels for receiving your codes. The available channels are:
SMS
App (e.g., Google Authenticator)
Hardware security key (U2F standard)
You can select a single, primary verification channel or combine the App/Hardware key with SMS, which can then serve as an alternative method.
Important: The 2FA configuration you set here is shared across the entire account. This means that the chosen authentication methods will be mandatory for all of its users.
Finally, save the configuration using the Save button. From that point on, during subsequent logins, the system will ask for the additional verification.
Information for Account Administrators
Enabling verification via SMS will trigger a system check to see if all users have phone numbers assigned. You will be notified of any missing information with an additional message.
With the SMS method active, providing a phone number is mandatory when adding new users to the account.
