Firefox-Lockwise: prompt user password to unlock Master Password

Question

I find Firefox's Lockwise default behavior, to be able to use and more importantly to see stored password, unsafe;
but having to type my Master Password every time is too much: for obvious comfort reason, but as well for security reason (typing all the time the same, important, password in public).

I would like a way to unlock the Master Password with my login password:

• because this password is less important (only local);
• and because I could use face-recognition or fingerprint to unlock it.

Is there any way to do that?

I'm using Ubuntu 18.04 LTS with GNOME 3.28 and latest Firefox (currently 70).
