Once Password is accepted as valid, any changes are accepted as valid.

1. Select Facebook to create an account
2. Enter a valid password
3. Change the password to something invalid
4. Or, try this, enter an invalid password to begin with, such as 4 letters

Bug
Once the password is accepted as valid, changing it to invalid, does not change the status. It still shows as valid.

Add check for invalid password. That is, if I type in 4 letters or less or I type in a password with a space, show the invalid symbol.

I tested this on Chrome.
