Otherwise databases may truncate the email without warnings, which
could lead to unpredictable or insecure behaviour. Long passwords may
also be very expensive to hash for certain algorithms.
## Options
* `:hash_password` - Hashes the password so it can be stored securely
in the database and ensures the password field is cleared to prevent
leaks in the logs. If password hashing is not needed and clearing the
password field is not desired (like when using this changeset for
validations on a LiveView form), this option can be set to `false`.
Defaults to `true`.
