Try in this order
- A recovery code you saved when you turned on two-factor.
- A phone or browser that is already logged in.
- A backup login method listed on the login screen.
- The identity flow Meta offers if none work.
Meanwhile
Ask a backup admin on the business portfolio to keep ads running and check payments. That is one reason to have a second admin.
Afterwards
Update the phone number, save new recovery codes and add a second admin.
