I lost access to my wallet, and did not write down my Backup Phrase. Can I get my wallet back?
If you did not import your Lumi wallet on any other device and you did not save a copy of your Backup Phrase, then yes, you have completely lost access to your wallet. This is why we urge you to back up your wallet.
