Add biometric security options to mobile apps

### What are you trying to do?

Hi,

I'm traveling to Mexico City in a couple of days and was reading about public safety over there. This got me thinking, what would happen if someone stole my phone, or got access to it otherwise. They could simply access all devices in my tailnet.

It would be great if the mobile apps would have a fingerprint unlock or facial recognition option for an extra layer of security.

Thanks

### How should we solve this?

Add biometric security options to all mobile apps

### What is the impact of not solving this?

Potential security risk

### Anything else?
