Watch asks for Apple ID Password
Recently my watch has been asking for my Apple ID password, which never happened before.
This has been happening when I put the watch back on. I have been clicking Cancel, the message reappears, and I click Cancel again. Then everything works fine -- no functionality is missing.
The Apple ID mentioned is my (only) Apple ID. My watch obviously believes my Apple ID since it can access my photos, and appointments, and can unlock my Macs.
It would be really inconvenient to enter my long, secure, Apple ID password on the watch. At no point previously was I ever asked to enter my password on my watch. This might have started with Watch OS 6.0.1. I also recently restored my iPhone from backup, and re-setup the Apple Watch.
Why is it asking for this now??

P.S. While typing this, I opened the Watch App on my phone, which triggered the watch to ask again for the password. Apparently, it happens every time the Watch App is opened, as well as when I put on the watch.
