I have a new Galaxy A17. My fingerprint sensor is working on all other apps, but Samsung Pass will not accept fingerprints. It appears initially to accept the fingerprint, then thinks for a few seconds, then comes back with a message "couldn't recognize finger print. Try again later." I have deleted and recreated all fingerprints, I have tried different fingers, I have tried software updates, nothing has worked. It appears initially to accept the fingerprint, then thinks for a few seconds, then comes back with a message "couldn't recognize finger print. Try again later. I've had this phone for several months, and Samsung Pass has never worked.
I contacted Samsung technical support, talked to four different people, and no one solved the problem for me. Tech Support handed me off to a different software support team, who told me I needed to talk to Tech Support. Samsung Tech Support has failed me on this one.
Solved! Go to Solution.
I think it is advisable to put thumb or finger in different positions and possibly take a few of them twice @Abee However @ETCottle has tried different fingers and as fine with other apps it may well be a specific issue with Samsung pass on their Device, hope you can get it sorted.

Update and bizarre coincidence...
After I posted the comment above, the very next time I tried Samsung Pass it told me that there was a software update. I had turned off the WIFI, that could have had something to do with it. The Samsung Pass software updated, and after that everything has worked fine.
So it was clear that the software needed to be updated, but it wouldn't tell me that till I tried over mobile data with WIFI off.
At any rate, the problem is now resolved.
Hello I have been having this same issue for over a year and can confirm that if you are having fingerprint registration issues for samsung pass just disconnect Wi-Fi for the agree and register screens then your good to go after that.
