2FA in the App

Good Idea and I love it. I forgot to take a backup of the 16 character code. What should I do if I buy a new phone and have to stop using my old phone ?

One way is to disable the 2FA in the Nash account and enable it with the new phone’s app. Is there any other way out of this issue, may be for people who loose their phones ?

EDIT : Got the answer for my case. The Backup code is stored in the app.
Hope people lost the phone has to contact support to get it reset.

Thanks !

This update made me realise I forgot to write down my 2FA backup for Nash so I just disabled mine and re-enabled like you said.
