Entering Apple ID password on an Apple Watch

For some reason, my Apple Watch asked me to enter my Apple ID password again today. But it’s almost impossible to because I can’t get it to distinguish between O, o, and 0 when hand drawing the characters.

I canceled the entry, but it’s still working, so one question I have is why does it want me to enter it?

I guess I can change my password to something with characters that can’t be mistaken. Like avoid those characters, and also 1 and l.
