Abstract
An authentication passphrase is analyzed to identify a first set of parts of speech in the passphrase. Based on comparing the first set with a second set of parts of speech corresponding to a stored passphrase, it is determined that the first set and the second set have less than a threshold number of common elements. In response to the determining, the passphrase is analyzed to score a level of a previously-set emotional tone in the passphrase. Access to a protected resource is allowed in response to the score being above a threshold.
