Comment puis-je modifier mon numéro de téléphone pour recevoir des messages d'authentification par SMS ?

SMS authentication is generally intended as a temporary two-factor authentication method. Once a permanent security device has been activated, such as IBKR Mobile Authentication / IB Key or a physical security device, SMS authentication is normally replaced by that permanent method.
For this reason, it is generally not possible to reactivate SMS authentication as the main login security method once it has been replaced by a permanent security device.
If you have changed your phone number, lost access to your previous number, or are unable to complete the login authentication process, please contact MEXEM Support. MEXEM can guide you through the available security device recovery or replacement procedure with IBKR.
