Various embodiments of the technology described herein alleviate the need to specifically request enrollment information from a user to enroll the user in a passive voice authentication program. The system can receive one or more spoken words from a user. The system can determine that a voice profile is usable for user authentication. The system can select at least one word from the one or more spoken words to enroll the user into a voice authentication program without requiring further interaction from the user. The voice authentication program enables access to secure data in response to receiving the at least one word spoken by the user. After enrollment of the user into the voice authentication program, at least one word spoken by the user is received, and the user is authenticated based on the at least one word.
