My backup is on a flashdrive with a QR in addition so I can scan it with an external device if needed. I'll never need it again until I get a new phone since I use amber. On desktop use nos2x. Hence the backlash for not having amber support. Because people like me are not going to go digging up their nsec just to try a new app... I already have it secure in amber. I know all the places it's at. If I go putting it in everything I try I now have to remember it's there and trust they some mishandle it.
