### Summary

Please add the option to open vault with device credentials for those that don't have fingerprint scanner

### Motivation

Many low end phones don't have fingerprint scanner so please if may add this feature.

I saw this feature in KeepassDX that it is also FOSS and is exist in F-droid.org.

Please if may consider adding this option, It is really great.

And because KeepassDX is FOSS, you can use its implementation or get idea that how they implemented this feature.
