It has two benefits
1- Is easier. Don’t worry if you forget your password,no more nightmares 
!! Just put your finger (another finger can be also recorded) and you are welcome again. Devices without fingerprint sensor can use another device with this sensor to verify and log in in the first one. Is similar to online shopping, where a sms or fingerprint/faceID data is necessary.
2- And safer. Each person has his/her own fingerprint, no one has the same. That means that if another person tries to use his/her fingerprint, system knows s/he isn’t the owner , sends a notification to the owner for further legal actions.
FaceID , however, isn’t secure at all. It can be bypassed with a photo.
Replace Password login for fingerprint
Enter your username or e-mail address. We'll send you an e-mail with instructions to reset your password.
Sounds good to improve security for people who use the mobile app.
