A man who forgot the password to a Bitcoin wallet containing around $400,000 worth of cryptocurrency has finally regained access after an 11-year search, with the help of Claude AI. Over eight weeks, Claude analysed his old college computer and discovered a wallet backup that could be decrypted using a mnemonic phrase, ultimately revealing the forgotten password — "lol420fuckthePOLICE!*:)" — which he had set while high back in 2015. The grateful owner, known online as "cprkrn," joked he would name his child after Anthropic CEO Dario Amodei in thanks.
