Overview
When you change your phone number, you have to update your account to send MFA codes to the new phone number. If you still have your old phone with the old number, you can manually change your MFA code destination. If you don't have access to your old phone, you can request an MFA reset to have ITS change the destination of your MFA codes for you.
Environment
Anyone who's changed their phone number and receives MFA codes over text messages.
Details
The self-service update button will take you to the security info page of your Etown account. Here you can change which phone number receives MFA codes. This option only works if you have access to your old phone number. Trying to access this page will require multi-factor authentication. To do a self-service change, click the Self-Service Update button at the top right.
