Abstract
Techniques for providing different levels of access based upon a same authentication factor are provided. A first message is received that is transformed with a first portion of a split private key, the first portion based upon a user password and another factor, and the split private key associated with an asymmetric key pair having a public key and the split private key. The user is authenticated for a first level of network access based upon the received first message being transformed with the first portion. A second message is received that is transformed with a second portion of the split private key, the second portion based upon the password only and not combinable with the first portion to complete the split private key. The user is authenticated for a second level of network access different that the first level based upon the received second message being transformed with the second portion.
