- Head to the More section of Celo.
Toggle Enable Touch ID on.
- Read and Accept the security warning pop-up that appears.
Touch ID is authenticated by your own device, and not by Celo. Anyone who has a recognised fingerprint on the device will be able to open Celo and access your messages.
- Do not enable this feature if you are unsure whose fingerprints are stored on this device.
- Enable this feature only if you agree that you are responsible for all Celo activity on this device, as set out in Celo's terms and conditions.
