As the print scans are stored locally, and this isn't Google we're dealing with, I didn't have a problem using that instead of repetitive code entry.
~ And this is coming from someone who refused to use such technology for ANYTHING before I got my S10+.
(Please note: Samsung is not getting my fingerprints. They're stored on my phone only.)
If you change your Lock Screen Type to Swipe, it disables your password. I would not recommend this as then anyone can get into your phone, but my recommendation may be irrelevant to you...
Settings | Lock Screen | Screen lock type | <Enter current Pin/Password> | Swipe (no security)
There are other types in Screen lock type that might work better for you, and still provide security.
