Abstract: A method (200) performed by a plurality of servers (108) to each provide a share (110) of a secret to an owner (102) of the secret is disclosed. The share of the secret (110) is generated using a cryptographic share generation method. The plurality of servers (108) each store a different share and an associated unique identifier indicative of the owner, the unique identifier having a corresponding verifier. Each of the plurality of servers receives a request (202) from a user (102) to provide the share stored by the server. The server identifies (204) the share stored by the server using a request identifier and further compares a request verifier to the verifier corresponding to the unique identifier associated with the stored share. If the request verifier suitably compares, the server authenticates (206) the user as the owner by providing the share (208) to the user.
