Enable Biometric Login

Tuya-powered OEM apps allow biometric login after this service is enabled. This way, users can log in to the apps without entering the account and password.

Advantages

• Enable quick login to the apps by using face recognition or fingerprint recognition provided by mobile phones. This service greatly improves the app user experience.

• App account security is enhanced. This service relies on the unique biological characteristics of individuals to verify they are who they say they are. Biometric authentication systems show more secure and confidential anti-counterfeit performance than other identity verification methods.

Prerequisites

• The template of Smart Life used by your OEM app must be v3.29.5 or later.
• The biometric login service plan is purchased.
• The biometric login service is enabled.

Set permissions

• iPhones that support face recognition: Open the app, choose Account and Security > Face ID, and then enable biometric login. Thus, when users attempt to log in to the app, the face recognition login page appears by default. Login is automatically enabled after the identity is verified.

  

• Android mobile phones that support fingerprint recognition: Open the app, choose Account and Security > Fingerprint ID, and then enable biometric login. Thus, when users attempt to log in to the app, the fingerprint recognition login page appears by default. Login is automatically enabled after the identity is verified.
