Its actually quite secure if you can throttle how fast you can try combinations of characters like we do with only allowing 5 attempts and then waiting 15 minutes, but if they have just the hash they can try many combinations very fast with a program. If you password is very random then it probably won't be found.

For instance lets say you had a password of just lower case letters and it was 8 letters long. that would be 23^8 == 78310985281 different possible passwords, that in the hackers "worse case" have to be tried and hashed, not impossible, but not trivial either. If you had upper case letters as well as lower case then 46^8 == 20047612231936 so even harder. This assumes that your password is just random letters, if you have some word or combination of words you can find in the dictionary, or a birthday, or something else common, then they could try these first and make the attack easier.
