# Security and preferences

> Two-step verification, sessions, your photo, language, the AI assistant setting and email summaries.

## Two-step verification

**1. Open Security**

Open your account menu (bottom of the left menu) and click **Security**.

**2. Add an authenticator app**

Scan the QR code with an authenticator app (Google Authenticator, 1Password, Microsoft Authenticator...) and type the 6-digit code it shows.

From then on, Kerux asks for a code from the app after your password or email code. A workspace owner can require it for every member.

To protect your account, Kerux limits sign-in attempts and wrong two-step codes in a short time. If you hit the limit, wait a few minutes and try again.

On the same page you can change your password, see your active sessions and click **Sign out everywhere**.

## Your photo

Open your account menu (bottom of the left menu), click **Preferences** and use **Your photo** (**Upload picture**, **Change** or **Remove**). It shows on your account menu and next to the campaigns you create, so your team knows who made what.

## Language and theme

Kerux is in English by default. To change the language from any page, open your account menu (bottom of the left menu; on a phone, **More**, then your email), click **Language** and pick English, Español, Deutsch or Français. The page switches at once and keeps anything you were typing. Kerux remembers your choice on every device you sign in on, and sends your emails in that language.

Kerux follows your device's light or dark setting until you pick a theme. You can choose the language, and the theme, in **Preferences** (account menu: **Theme** with **Same as this device**, **Light** or **Dark**); pick **Same as this device** to follow your device again. On the public pages, the two buttons at the top right change the language (such as **EN**) and switch between light and dark in one click (the sun or moon; on a phone, open the menu). In the app, use the sun and the moon at the top left, under the Kerux logo (on a phone, the sun or moon in the top bar).

## AI assistant

When a contact needs you, **Kerux AI** speaks first: it says what happened and offers the fixes (see [Follow your contacts](/help/campaigns/follow-your-leads.md)). To have it answer only when you ask, open your account menu (bottom of the left menu), click **Preferences** and, under **AI assistant**, untick **Proactive**. It's on by default and only changes what you see, not your teammates.

## Weekly summary email

Owners and admins get a summary of the week's results on Mondays (only when there was activity). Turn it off or on in **Preferences**.
