Tips for Reliable Fingerprint Access For children, seniors, or anyone whose fingerprints may change or wear down over time, we recommend re-enrolling fingerprints every few months for more reliable access. For seniors or users with worn fingerprints, registering multiple fingers can provide more options and improve everyday unlocking convenience.
