Authentication manager

Implementations

impl AuthManager

pub fn new() -> Self

Create new authentication manager

pub fn with_policy(policy: PasswordPolicy) -> Self

Create with a specific password policy.

pub fn set_password_policy(&self, policy: PasswordPolicy)

Set the password policy.

pub fn get_password_policy(&self) -> PasswordPolicy

Get the current password policy.

pub fn create_user( &self, username: &'static str, password: &str, ) -> Result<UserId, KernelError>

Create new user account.

Validates the password against the active policy before creating the account.

pub fn authenticate(&self, username: &str, password: &str) -> AuthResult

Authenticate user.

Checks account lock, expiration, password, and MFA status.

pub fn authenticate_mfa( &self, username: &str, password: &str, mfa_token: u32, ) -> AuthResult

Authenticate with MFA

pub fn change_password( &self, username: &str, old_password: &str, new_password: &str, ) -> Result<(), KernelError>

Change a user’s password.

Validates the new password against the active policy and checks password history to prevent reuse.

pub fn set_account_expiration( &self, username: &str, expires_at: Option<u64>, ) -> Result<(), KernelError>

Set account expiration.

pub fn enable_mfa(&self, username: &str) -> Result<[u8; 32], KernelError>

Enable MFA for user

pub fn unlock_account(&self, username: &str) -> Result<(), KernelError>

Unlock user account

pub fn delete_user(&self, username: &str) -> Result<(), KernelError>

Delete user account

pub fn list_usernames(&self, buf: &mut [Option<&str>]) -> usize

List all usernames. Returns an iterator-friendly fixed-size collection.

Since we cannot return Vec<String> without heap allocation, callers should use with_users or iterate via the returned array.

pub fn get_user_by_id(&self, user_id: UserId) -> Option<&'static str>

Get user by ID
