This guide shows how to make every sign-in to your organization a two-step one. After the password or the usual sign-in, each person also enters a code that Instafill.ai sends to their phone by text message. You turn it on once, for everyone in the organization.

## What you need before you start

| You need | What that means |
|---|---|
| **The Owner or Admin role** | Only an Owner or an Admin of the organization sees the setting. |
| **A phone that receives text messages** | Each person in the organization needs one to sign in once the setting is on. |

## 1. Open Authentication security

Click your initial in the top right corner and choose **Profile**. In the list on the left, under **Organization**, click **Authentication security**.

## 2. Require two-factor authentication

Tick **Require two-factor authentication for everyone in your organization.** The change is saved at once. There is no Save button.

From then on, everyone working in your organization is asked for a code each time they sign in, you included. A person who is already signed in is asked for a code before they continue, and may be asked to sign in again first.

## 3. Add a phone number the first time

The first time a person signs in after the setting is on, the **Two-factor authentication** screen asks for a phone number.

- **The number**: Type it with a plus sign and the country code first, as the box shows.
- **The code**: Press **Send code**. The number is kept for the next sign-ins.

## 4. Enter the code from the text message

A text message from Instafill.ai brings the code. Type it under **Verification code** and press **Verify and Continue**. The app opens.

On later sign-ins the screen shows the saved number with only its last digits visible. Press **Send code**, then enter the code as before.

- **No message arrived**: Press **Resend code** for a new code. If the screen asks you to wait, press it again a little later.
- **A new phone**: Press **Change number** under the saved number and type the new one.
- **Enter the code soon after signing in**: If more than 5 minutes pass, you are asked to sign in again.

## Turn it off again

Open **Authentication security** and clear the tick. From then on, nobody in the organization is asked for a code.

## People who belong to several organizations

The setting applies while a person works in your organization. If they switch to another organization that does not require it, they are not asked for a code there.
