I have the Apple Watch SE 2nd generation and it never charges up to 100%. It did it at first, but won’t now even on another charger. Also, it asks for my passcode ALL the time and it is aggravating!

Did you check the settings for Optimized Charging?
You can disable this feature and charge your watch to 100% each time you put it on the charger.
Have a look at the related article, in which it is also being explained, why Apple introduced this option:
About Optimized Battery Charging on your Apple Watch - Apple Support
As for the passcode, did you make sure that Wrist Detection is enabled and that there are no tattoos underneath the sensors?
Lock or unlock Apple Watch - Apple Support
Why is my Apple Watch SE not charging to 100% and asks for my passcode often?
