Local Brave Wallet Lost

Local Brave wallet lost after factory resetting pc. I did not save my secret passphrase but my local brave metamask wallet was synced automatically every time I opened the browser. Is that wallet gone forever since there is no way of recovering it without the secret passphrase?
Thanks.,
