One method includes determining a use context of the communication device and an authentication status of the communication device. The method further includes determining a predetermined period of time based on at least one of the use context and the authentication status. The method further includes generating biometric templates based on at least one of the use context and the authentication status. The method further includes selecting a matching threshold for the biometric templates based on at least one of the use context and the authentication status. The method further includes comparing a match score of each of the biometric templates to the matching threshold to determine a passing amount of biometric templates with match scores that meet or exceed the matching threshold. The method further includes authenticating the session on the communication device.
