# Account Security

> Your profile, passkeys, two-factor authentication and password.

Go to **Settings**. The **Account** part of the settings menu has your personal settings. They apply in every organization you belong to.

![Personal settings with the Profile section](https://mintcdn.com/hyperstack/BRB0JNPJFl2Fq7-q/images/settings-personal.webp?fit=max\&auto=format\&n=BRB0JNPJFl2Fq7-q\&q=85\&s=661f356e1faa6415cedc33786ae93526)

## Profile

Change your **full name** and **username**. Your name appears on the credentials you receive and in your wallet. You sign in with your email, which you can't change here.

## Ways to sign in

* **Email and password**.
* **Sign in with Google**.
* **Passkey**: sign in with your face, fingerprint or device PIN.

## Passkeys

A passkey only works on Hyperstack, so it can't be phished. Under **Passkeys**, add one for each device you use. You need a current version of Chrome, Safari, Edge or Firefox.

## Two-factor authentication

Two-factor authentication protects your account if someone learns your password.

**1. Under Two-factor authentication, click Set up**

You need an authenticator app on your phone, such as Google Authenticator, Microsoft Authenticator or Authy.

**2. Scan the QR code with the app**

Can't scan it? Enter the setup key in the app.

**3. Enter the 6-digit code from the app and click Verify and turn on**

We then ask for a code from your app each time you sign in with your email and password. Keep the app: if you lose it, contact support to get back in.

## Password

Enter your current password and the new one, then click **Update password**. The password needs at least 8 characters, with an uppercase letter, a lowercase letter, a number and a special character. Changing it signs you out everywhere else.
