My son who was an avid bit-coiner just passed away suddenly (couple of weeks ago), he has mentioned in earlier conversations that he has a "large" amount of BTC in several encrypted wallets. He was using Ledger and Razor - I found the keys and recovery sheets among his belongings, but not a password. Is there a way that the Ledger and/or Razor sites may be approached to access his account since I do have most of the info for the account? Any help or guidance will be appreciated.
