Claim:
1. A method of operating an authentication system, the method comprising: receiving, by processing circuitry of the authentication system, an enrollment request to enroll a user in a new authentication procedure in place of an earlier-established authentication procedure, the earlier-established authentication procedure being operative to authenticate the user at a first security level within a range of security levels, the new authentication procedure being operative to authenticate the user at a second security level within the range of security levels, the first security level being at least as high as the second security level within the range of security levels; in response to the enrollment request, initiating, by the processing circuitry, the earlier-established authentication procedure to authenticate the user; in response to completion of the earlier-established authentication procedure, performing, by the processing circuitry, an authentication enrollment operation associated with the new authentication procedure; and verifying, by the processing circuitry, that the first security level is at least as high as the second security level, wherein performing the authentication enrollment operation associated with the new authentication procedure is carried out only after successfully verifying that the first security level is at least as high as the second security level.
