Fingerprint authentication in Android app wrapping a web page
<p>I have a webpage that needs authentication which can be tedious to enter on mobile so I was thinking of creating a wrapper application that could login the user (only one - me) automatically with saved credentials. In order to protect the credentials I want to use the fingerprint API (I use a Samsung S5). However this is new stuff for me so I have few questions about the feasibility:</p>

<ul>
<li>Is it possible to automatically log into a web page from an app wrapper?</li>
<li>Could this work with a non-trusted certificate (I have to generate my own)</li>
<li>Can I encrypt and use the fingerprint to decrypt the credentials so they are secure on the phone?</li>
</ul>
