Description

This pull request adds a password-change API and POST /password/change endpoint. Authenticated users can update a credentials account password after the server verifies the current password.

Key Changes

• Add changePassword to the server API, with request validation, session checks, redirect handling, and secure response headers.
• Add and register the password-change endpoint.
• Add password verification and update logic for stateful sessions, plus an unsupported-operation handler for stateless sessions.
• Add API types, request and response schemas, and an INVALID_CURRENT_PASSWORD error.

Usage

const { success } = await api.changePassword({
  payload: {
    currentPassword: "current-password",
    newPassword: "new-password",
  },
});

Walkthrough

This change adds password updates for stateful sessions through a programmatic API and a POST /password/change endpoint. It validates current and new passwords, verifies the current password before storing a hash of the new password, and marks the operation unsupported for stateless sessions.

Merge Risk: Low · up to fadba

Applications using a custom session adapter could allow password changes from an inactive or expired session if the requester also has the current password and a CSRF token. The risk is bounded, but session status should be checked before relying on it.
