I lost my 2FA app today. Unfortunately, I had not saved the backup codes for my account https://en.wikipedia.org/wiki/Special:CentralAuth/Vahagn_Petrosyan. I am still logged in to my account on desktop.
I wrote an email to ca{{@}}wikimedia.org from the email address that is attached to User:Vahagn_Petrosyan.
Please remove 2FA from User:Vahagn_Petrosyan
