Simplify the default admin password.

Easier to type and remember: if I mistype this one more time I will....... :rage: 

Downside: lose the indication that your password should have uppercase and special chars.

But if an admin does not know that, then that is the least security concern for the users... so I it's worth having the simpler password.

The real solution to stronger passwords for all users is to add a password strength indicator.
Prefer single-quoted strings when you don't need string interpolation or special symbols.
