If you are logged into your Guardify account and need to update your phone number to a different number, you are able to change your own phone number from your user settings.
After you've logged in, click the company name at the top left above the navigation menu, where your name is displayed.
On the user settings screen that appears, click the "edit" button in the bottom right corner.
In the grey box that shows your phone number, click the pencil icon that appears to the right.
You will then be prompted to type in your new phone number twice. Click done.
The prompt will close, and then you will need to click save.
You will then be prompted to confirm your changes with a 6-digit verification code. This code will be sent to your new phone number.
Next time you log in, you will receive your text code to your new number.
