Please I need help

Hello everyone please help me it’s been a month I can not access my Facebook account I used mobile duo authentication but all the codes I receive do not work I do not know what to do

It sounds like you were using Duo as a code generator for Facebook. Please contact Facebook support for help with regaining access to your account.

In the future, we recommend generating and saving recovery codes (https://www.facebook.com/help/148104135383285?helpref=faq_content) for third-party accounts like Facebook and using Duo Restore for Third-Party Accounts (https://guide.duo.com/duo-restore#android).
