## Users

User management covers login, registration, invitations, and access control within an account.

## Login

- Login with email or username and password
- Optional **two-factor authentication (2FA)** — after entering the password, a one-time SMS code sent to a verified phone number is required
- The system tracks the date of last login and the number of failed attempts

## Registration and Invitations

- New users can be **invited** by email — the invitation contains an activation link valid for 7 days
- The invitation specifies the user's role (owner, admin, user, guest)
- If the invited user does not have an account — they must register
- If they already have a guest account — their role will be upgraded
- A single user can belong to multiple accounts

## Verification

- **Email** — address confirmation via an activation link (token valid for 24 hours)
- **Phone** — number verification with an SMS code (code valid for 10 minutes)
- A verified phone is required to enable 2FA

## Permissions

Each user has an assigned **role** that defines a set of permissions (see the *Roles* entry). Permissions control access to modules, features, and operations in the system.

An administrator can manage users — change their roles, deactivate accounts, reset passwords.

## Guests

Guests are users with limited access. A guest account is subject to **moderation** — an administrator must approve or reject guest access. Moderation statuses: pending, approved, rejected.

## Deleting an Account

A user can delete their account — data is anonymized (soft delete), but the activity history is preserved.
