# Change your multi-factor authentication (MFA) method

> Change your Chartnote multi-factor authentication method to text message (SMS), an authenticator app or an email code in Settings, then Account & Security.

Choose or change how you get multi-factor authentication (MFA) codes: text message (SMS), email code or an authenticator app.

**Who this is for:** People who sign in with email and password · **Plans:** All plans · **Where:** Web (app.chartnote.com)

> [!NOTE]
>
> If you sign in with Google, Chartnote doesn't manage your MFA. Settings shows that your identity provider manages it, so use your Google account settings instead.

## Change your MFA method

**1. Sign in at [app.chartnote.com](https://app.chartnote.com).**

**2. Click your avatar in the bottom-left corner to open the account menu.**

**3. Open **Settings** → **Account & Security**.**

**4. Set up the method first. For **Text message (SMS)**, enter your mobile number under **Add or Change Phone Number** and click **Validate phone**. For **Authenticator app**, go to **Enable Authenticator App**, click **Generate QR**, scan the code with your app, and enter the 6-digit code.**

**5. In the **Multi-Factor Authentication setup** card, select **Text message (SMS)**, **Authenticator app** or **Email code**.**

**6. Click **Save** in that card.**

### Other options

* **Add or Change Phone Number**: update the number used for SMS codes.
* **Generate QR** (in **Enable Authenticator App**): set up the authenticator app again, for example on a new phone.

> [!NOTE]
>
> Email codes aren't offered when you first sign up. Once you've created your account and signed in, you can choose **Email code** here.

Want to stop using MFA instead? See [Turn off multi-factor authentication (MFA)](https://docs.chartnote.com/account-and-security/turn-off-mfa.md).
