If you see under "Profile" and "Two-factor authentication" on the device you are using that it is not your linked device, there may be various reasons for this.
Changing your device or deleting the app when two-factor authentication (2FA) is activated can cause the link to a previously linked device to be lost.
If you have your backup code for deactivating 2FA, you can enter it by clicking on the "Deactivate" and "No access to linked device" button and then link your device again.
If you do not have your backup code, please contact our client service at service@scalable.capital.
