Enable biometric login (remember login details)

[LindsayRaabe_FPCWA]

I find many apps now allow you to let your mobile device remember your login details and instead use your biometric infomation (fingerprint/facial recognition/iris scan). This would be a useful feature for logging into Field Maps instead of having to retype your username and password everytime.

This is very essential for field workers who will not have to mess with passwords,

Although it seems like a small and marginal detail, it sometimes becomes disturbing and annoying.

I think it makes logging into a device faster and more effective. I sometimes get lost when I have to go back to my device and cut and paste my information.

I think facial recognition is the way to go.
