How do you use biometric sensors? #216

Sorry for the interruption, I have a question that hasn't let me sleep, I don't need to authenticate the user, I just want to be able to obtain the fingerprint through the sensor.

I have tried to do it, but I have not been able to fully understand how to access it, from what I understood, android only exposes the authentication services and the fingerprint information is handled in the exclusion zone.

My question is, do you have any ideas on how I can get the fingerprint of the user so I can use it later?

If you don't have an answer to my previous question, can you explain to me in broad terms how you handle user authentication? Do you only use android services or can you control the sensor directly with your plugin?

Hi @JoseCarlosBran,

I'm the friendly issue checker. It seems like (100.00 %) you haven't used our issue template :cry: I think it is very frustrating for the repository owners, if you ignore them.

If you think it's fine to make an exception, just ignore this message. But if you think it was a mistake to delete the template, please close the issue and create a new one.

Thanks!

The mobile OS don't give you control over the fingerprints directly, because it's very sensitive data. This information is usually stored in a secured hardware enclave. So I think even the OS can't read this data. Only write and delete.

Maybe It would be interesting to create a discussion section so people can ask away their questions don't you think? 🙂
