Keeping up with security standards, Telnyx has implemented a TOTP (time-based one time password) login feature for the Mission Control Portal.
You can enable TOTP in the Account section of the Mission Control Portal:

Set up your TOTP authentication application by scanning the QR code shown in your account settings. Once scanned you will see a temporary authentication code in your TOTP authentication app. Enter the code underneath the QR code to activate TOTP on your Mission Control account.

Telnyx TOTP will work with all standard TOTP applications. We recommend using Google Authenticator. You can download the Google Authenticator app via the Apple AppStore or Google Play. To set up your Google Authentictor app, simply scan the QR code shown in the Mission Control Portal and enter the temporary code that shows up on your mobile device. That's it, now TOTP has been enabled on your Mission Control Portal. Upon signing in, you can enter the temporary code that shows in your Google Authenticator app when prompted to do so.
