# Your account and security

Keep your details and addresses up to date on the portal, change your password, turn on two-factor authentication, add a passkey, sign out other devices, or delete your portal account.

A client keeps their own details, addresses and sign-in security up to date from the portal. The details are those of the client's contact in the firm, so the firm sees each change. Nothing is saved on the screens below.

## Before you start {#before-you-start}

- You are signed in to the portal: [Give a client portal access](give-a-client-portal-access).
- The firm's own users manage their security in the back office: [Set your preferences](/docs/essentials/set-your-preferences).

## Your details {#details}

On the home page of the portal, the card with your name shows your address and e-mail; click **Edit information** under it. Your name at the top of every page opens a menu with **My Account**, the home page, and **Logout**.

The form holds **Your name**, **Email**, **Phone**, **Company Name** and **VAT** for a client who buys as a company, **Street and Number**, **Apartment, suite, etc.**, **City**, **Zip Code**, **Country** and **State / Province**. Leave **Electronic format** empty unless your software reads structured e-invoices. The fields marked with a star are required. Once the firm has issued documents to you, the **Country** is locked: ask the firm to change it. **Save Address** keeps the changes; **Discard** leaves without saving.

## Your addresses {#addresses}

**Addresses** on the home page lists your **Delivery address** cards. The main one carries **Main Address**; the pencil of a card opens the same form to change it, and the bin removes a card other than the main one. **Add Address** adds another address.

Under **Billing address**, **Same as delivery address** is on: invoices go to the main address. Turn it off to show the billing addresses and add one for the invoices.

![The delivery addresses with the main address, and the billing address, here the same as the delivery address.](https://jaah.app/web/image/16934-c86fcd0b/client-portal-your-account-and-security-addresses-en.png)

## Connection and security {#security}

**Connection & Security** on the home page gathers the sign-in settings.

- **Change Password**: type the current **Password**, then the **New Password** twice, and click **Change Password**. The eye button next to each box shows what you typed.

![Connection & Security; the password first, then two-factor authentication, passkeys, sessions and the account.](https://jaah.app/web/image/16938-b282bac9/client-portal-your-account-and-security-security_page-en.png)

- **Two-factor authentication**: after the password, each sign-in asks for a six-digit code from an authenticator app on your phone. Click **Enable two-factor authentication**. A **Security Control** window first asks for your current password, then shows a code to scan with the app; **Cannot scan it?** shows a key to type into the app instead. Type the code the app gives and click **Activate**. The section then says that two-factor authentication is enabled and offers to disable it. At sign-in, **Don't ask again on this device** skips the code on a device you trust.

![Before any change to the account's security, the portal asks for the current password.](https://jaah.app/web/image/16942-ec9ea8bd/client-portal-your-account-and-security-identity_check-en.png)

- **Passkeys**: a passkey signs you in with your device's own lock, a fingerprint, a face or a PIN, or with a security key; the sign-in page offers **Use a Passkey**. Click **Add Passkey**, confirm your password, name the key, click **Create** and confirm on your device. The table shows when each key was **Created** and **Last Used**; the pencil renames a key and the bin deletes it.

![The passkeys of the account, none yet, and the button that adds one.](https://jaah.app/web/image/16946-42afb867/client-portal-your-account-and-security-passkeys-en.png)

- **Revoke All Sessions**: **Log out from all devices**, after your password, signs out every other device where your account is open; this one stays signed in.
- **Delete Account**: the window asks for your password and for your login typed again, and its box, ticked by default, puts your e-mail and phone in a block list against further mailings. The red **Delete Account** disables the account for good; **Cancel** leaves it untouched.

![Deleting the account asks for the password and the login typed again; Cancel leaves it untouched.](https://jaah.app/web/image/16950-5c13a838/client-portal-your-account-and-security-delete_account-en.png)

## FAQ {#faq}

### I forgot my password. {#forgot}

Click **Reset Password** on the sign-in page: a link to choose a new one reaches your e-mail.

### I lost the phone with my authenticator app. {#lost-phone}

Ask the firm: an administrator turns two-factor authentication off on your user. Sign in with your password, then enable it again with the new phone.

### What does the firm keep when I delete my account? {#after-delete}

Your sign-in is removed and your contact is archived; the documents the firm issued to you stay in its records. To come back, ask the firm for a new access.
