Hashicorp Vault uses it. https://learn.hashicorp.com/tutorials/vault/rekeying-and-rotating https://learn.hashicorp.com/tutorials/vault/rekeying-and-rot... > In order to prevent one person from having complete access to the system, Vault employs Shamir's Secret Sharing Algorithm. Under this process, a secret is divided into a subset of parts such that a subset of those parts are needed to reconstruct the original secret. Vault makes heavy use of this algorithm as part of the unsealing process.
