Lost my 2FA key

[janjan22]

Dear all. Accidently I deleted one entry in the google authenticator app. It was used for extra security on an exchange website. Is there any way to get this entry/key back in the app after it is deleted? I dont have the seed or QR code anymore

sorry to hear that but you cannot access your account anymore by yourself . There is only one way now to get back your account is to contact with exchange website through support ticket . Hopefully you will get your account back.

Yeah OP should contact the exchange's support. A friend of mine lost his phone with google authentication installed on it. Hopefully he recovers after several days of waiting and followups.OP, please do email them now.

Support could be help but you need to prove that you own that account they will government ID just prove that you own the account if your name and the name of your account are same they will let reset your wallet and receive the reset link to your wallet..
But if you can't prove that you own that account your ip can be ban base on what i heard to other people experienced..
