# Account security

> Manage your password, two-factor authentication, and account preferences

Open your account menu at the bottom of the sidebar and click **Settings** to manage your account. Settings has two tabs: **Account** and **Security**.

## Account

Your personal preferences: profile photo, name, phone number, timezone, language, theme (system, light, or dark), and how many rows tables show per page.

## Security

### Two-factor authentication

Two-factor authentication is required to use the portal — you set it up during [your first login](/getting-started/first-login). From the **Security** tab you can:

* See whether your authenticator app is configured.
* **Enable 2FA** — scan a QR code with your authenticator app and confirm with a code.
* **Disable** your current authenticator setup — for example to switch to a new phone. You'll be asked to set up two-factor authentication again on your next sign-in.

### Change your password

1. Enter your **Current Password**.
2. Enter a **New Password** that meets the requirements shown: at least 8 characters, with an uppercase letter, a lowercase letter, a number, and a special character.
3. Confirm it and click **Update Password**.

<Tip>
  If you've lost access to your authenticator app and can't sign in, [contact support](/support/contact) — they can verify your identity and reset your two-factor setup.
