A 10 character password is not a problem.
Are there also rules for what type of characters must by included or excluded?
I agree with DieselD that it would be nice to not be forced to change it periodically.
My current password here is 13 characters. I wouldn’t think folks wouldn’t mind 10. Dibs on 1967Cougar 
Damn. I will have to change my password from “Password”, as it is only 8 characters. Hmmm…maybe AdminPassword would work?
I have 11 characters and I’ve found that Firefox’s password manager works well,
