* Additional notes regarding the $user->pass property:
|
|||
|
|
* Note that when getting, this returns a hashed version of the password, so it is not typically useful to get this property.
|
|||
|
|
* However, it is useful to set this property if you want to change the password. When you change a password, it is assumed
|
|||
|
|
* to be the non-hashed/non-encrypted version. ProcessWire will hash it automatically when the user is saved.
