Abstract
An embodiment of the invention includes an interface that receives a user identifier, and a processor that identifies the number of characters in the password for the user identifier. The interface receives input such that the number of characters in the input is greater than the number of characters in the password. The interface can receive additional input such that the number of characters in the additional input is greater than the number of characters in the password. The processor can compare the password to the first X characters of the input, where X equals the number of characters in the password. The processor can compare the password to the last X characters of the additional input. The processor can determine whether to authenticate the user based on the comparison of the password to the first X characters of the input and the last X characters of the additional input.
