/**

* For users that can be authenticated using a password.
1616
*
17+
* The __serialize/__unserialize() magic methods can be used on the user class to prevent the password hash from being
18+
* stored in the session. If the password is not stored at all in the session, getPassword() should return null after
19+
* unserialization, and then, changing the user's password won't invalidate its sessions.
20+
* In order to invalidate the user sessions while not storing the password hash in the session, it's also possible to
21+
* hash the password hash before serializing it; crc32c is the only algorithm supported. For example:
22+
*
23+
* public function __serialize(): array
24+
* {
25+
* return [$this->username, hash('crc32c', $this->password)];
26+
* }
27+
*
28+
* public function __unserialize(array $data): void
29+
* {
30+
* [$this->username, $this->password] = $data;
31+
* }
32+
*
33+
* Implement EquatableInteface if you need another logic.
