I am using a MD5 hash code to encrypt passwords

Is it possible to reverse this type of hash code?
 
The idea behind MD5 is it is a one-way hashes. The hash is designed to be
"computationally infeasible" to reverse. For smaller bits of information, it
might (with lots and lots of programming) be possible to reverse it, but it
would not be worth the time.

When you use MD5 for a password, the password is set to be unretrievable. To
determine if a person typed in the correct password, you compare the stored
hash to the hash of what the person put in. If they lose their password, you
send out a temporary password and they have to log in and change it.
