Thank you for your post.
At this time, it is not possible to login to a FileMaker Pro database using TouchID.
I recommend that you enter this suggestion into our Feature Requests web form at:
The entries into this web form populate a database file that is hosted and monitored by Product Management and Development. All web entries are read, discussed and considered for possible implementation in a future release. Although I could easily copy your post and paste it into the web form, there are a couple of questions asked on the form that only you can answer.
