     - **Do not** override the Argon2 type when implementing the argon2-cffi hashing library.
       ```python
-        ph = PasswordHasher(Type.I) // unsafe
+        ph = PasswordHasher(Type.I) # unsafe
         hash = ph.hash(user.password)

     - **Do** rely on the default Argon2 type (Argon2id) as it is the most secure. This ensures the highest level of security for password storage.
