Nope. Changing password to a password of similar complexity every 10 seconds doesn't make it much less likely to be guessed than a static password. It may mean you can't guess it again, but you generally don't want an attacker to even log in once.
One-time passwords, using a key generator may be better for other reasons for example, more entropy than "31137" or other passwords that users might pick, or be able to remember.
