Facebook authenticator problem

,

Topic summary

A user encountered a Facebook authenticator error when attempting to set up Facebook ads for their Shopify store. The error message indicated Facebook didn’t recognize their device, blocking them from making changes to their account.

The Problem:

  • Error stated: “You can’t make this change” due to using an unrecognized device
  • User was confused since they were using the same mobile phone and computer as usual

The Solution:

  • The user resolved the issue by using an older mobile phone instead
  • They accepted all new device alerts in Facebook (checking “this is me”)
  • Facebook apparently needed more time (beyond 2 months) to recognize the newer device as trusted

The issue appears resolved after switching devices and confirming identity through Facebook’s security alerts.

Hello, don’t know where to find a help, my question is due to facebook authenticator problem. I wanted to start my facebook ads for my shopify store, and somehow it started to show an authenticator error -

“You can’t make this change This is because we noticed you are using a device you don’t usually use and we need to keep your account safe. we’ll allow you to ma
ke this change after you’ve used this device for a while.”
I use the same mobile phone and the same computer.
How do i fix this?

Thank you! I guess 2 months mobile phone is not enough time for facebook, so i have just took my old mobile phone, accepted in facebook all alerts of new devices (checked “this is me”) and it helped. Thanks!
