If you are no longer logged in to your TenX account on any device and need to reset 2FA for your account, please see this article.
After successfully unlocking your TenX app, browse to Settings from the left pop-out menu while on the Home screen.
Tap the option to Reset two factor authentication. After confirming, you will be logged out of your account, and sent an email and an SMS (if a verified mobile number exists on your account) containing a 6-digit code.
When you next login to the TenX app, you can enter this 6-digit code to reset 2FA on your account. After successfully entering the code, you will be guided through the 2FA set-up process again.
