Abstract: A method for securing a split private key (such as used with a cryptocurrency or other non-custodial electronic wallet) amongst a password, biometrics, and a social service. The process may use a sharding scheme such as Shamir's Secret Sharing to ensure that multiple key shards must be obtained before the entire private key can be obtained. The user may select the number of shards required to retrieve the private key thereby controlling the security of the account. An additional shard may be held on an encrypted server and allows for account recovery even while maintaining non-custodial ownership of the wallet.
