Every time you clasp your Nymi Band on your wrist, you must authenticate yourself before being able to use it. Once you unclasp your Nymi Band, you are no longer authenticated.
Today, there are three options for authenticating to your Nymi Band:
- HeartID™. The Nymi Band can authenticate you based on your heartbeat (ECG). When you clasp the Nymi Band on your wrist and place your finger on the top sensor, it reads your ECG and can authenticate you without requiring the Nymi Band app or any mobile device to be present.
- Fingerprint. If your phone has a fingerprint sensor, you can use that modality to authenticate to your Nymi Band through the Nymi Band app.
- Password. This is facilitated through the Nymi Band app.
One, two, or all of these authentication methods may be selected during Nymi Band setup, and can always be changed from the Settings section of the Nymi Band app.
