If you still have the recovery codes you received when setting the 2FA on your GV account please follow the instructions here.
In case you have accidentally lost your 2FA device, you will not be able to disable 2FA from your account even after logging in.
You would need to e-mail us to support@genesis.vision and request to disable 2FA enabled on your account.
Please keep in mind, that we might ask you to send us specific documents to confirm your identity.
