Question

What technique creates different hashes for the same password?

Answer 1

The technique that creates different hashes for the same password is Salting.

A Salt in Cryptography is rаndоm dаtа thаt is used аѕ аn аdditiоnаl inрut to one way function, beside the original password.

This helps to safeguard against bruteforce and rainbow table attacks in which a hacker/cracker matches the most commonly used passwords' hash against database of commonly used passwords.

Hope it has helped

Answer 2

The answer is salted password hashing.

The salted password hashing technique creates different hashes for the same password. If two people use the same password that has been hashed twice, each time the hashes are different.

Salt is a random string, which is appended to either the start or the end of the password before hashing is done. This causes the hashes to be randomized and changes the same password into a different string each time the hashing takes place.
