What is the maximum number of profiles can be added in mAadhaar App?

A user can add maximum 3 profiles in his device, all having same mobile number registered in their Aadhaar. Auto-fill OTP is valid and hence user cannot add any profiles which are registered with any other mobile number. If members of your family have the same mobile number registered as you in their Aadhaar, you can add their profile in your device.
