One embodiment is described of a method performed by a computing device for renewing a remote token. The method includes (a) receiving an activation code from the remote token across a network, the activation code including an identification of the token, (b) verifying that the activation code was cryptographically generated with reference to a one-time passcode (OTP) generated by the identified token using an initial key assigned to the token, and (c) in response to verifying, negotiating a new key with the token, the new key to be assigned to the token for use in producing OTPs in the future. Related computer program products, systems, and apparatuses are also described.
