Signals from User Model

The lback.auth.models.User model emits several signals during critical user-related operations, such as password management and email verification. These signals offer valuable integration points for auditing user actions, triggering notifications, updating external systems, or implementing custom logic tied to user authentication and account management flows.

Signal Name	Description	Arguments (kwargs)
user_password_set	Emitted successfully after a user’s password has been hashed and set on the user model.	sender (User): The instance of the User model whose password was set.<br>``user`` (User): The User object itself.
user_password_set_failed	Emitted if an error occurs during the process of hashing or setting a user’s password.	sender (User): The instance of the User model on which the password set failed.<br>``user`` (User): The User object itself.<br>``exception`` (Exception): The exception object that caused the failure.
user_password_checked	Emitted after a user’s plain text password has been checked against the stored hashed password.	sender (User): The instance of the User model whose password was checked.<br>``user`` (User): The User object itself.<br>``success`` (bool): True if the password matched, False otherwise.
user_password_check_failed	Emitted if an error occurs during the process of checking a user’s password (e.g., due to an issue with the hashing library).	sender (User): The instance of the User model on which the password check failed.<br>``user`` (User): The User object itself.<br>``exception`` (Exception): The exception object that caused the failure.
user_email_verification_token_generated	Emitted after a new email verification token has been successfully generated and assigned to the user.	sender (User): The instance of the User model for which the token was generated.<br>``user`` (User): The User object itself.
user_email_verified	Emitted when a user’s email address has been successfully verified using a valid token.	sender (User): The instance of the User model whose email was verified.<br>``user`` (User): The User object itself.
user_email_verification_failed	Emitted when an attempt to verify a user’s email address fails (e.g., due to an invalid or expired token).	sender (User): The instance of the User model for which email verification failed.<br>``user`` (User): The User object itself.
