I wanna use argon2id(in php) for hashing my users password, But the problem is argon2id don't get static data

For example when you write:

echo password_hash("Hello", PASSWORD_ARGON2ID);
echo password_hash("Hello", PASSWORD_ARGON2ID);

The results is:

$argon2id$v=19$m=2048,t=4,p=3$Qowhgdak+Khdoae9#dhsowowhqj020euddwi0OwhsJa $argon2id$v=19$m=2048,t=4,p=3$pshapHzuaOwghdoeaiauw9hsyz72iqna029eh3opadjdk

And you can see when you call hash, argon2 give you another data per call

My question is how to use this for hash password?

How to fix that? Use salt option? But php is not suggested this

Note: we hash passwords and for login and others we hash the user entered password And we compare the two

Argon2 is the best for hash but I don't Kwon how to use it

  • That's how password hashing works when done right. You don't want a leaked database to make it obvious what users have the same password, nor allow hackers to use a precomputed hash list. – Álvaro González Jan 15 '23 at 10:27
