How can I change my email address?

Update your contact details: change the email address of your X4T account in a few minutes

Good news: you can now change the email address of your X4T account yourself, directly in your account settings. It takes about 5 minutes. Your account, balances and trading history stay exactly as they are, so there is no need to open a new account.

Before you start

Please make sure you have:

• Access to your X4T account. You need to be able to log in.
• Two-factor authentication (2FA) turned on with an authenticator app (for example Google Authenticator, Microsoft Authenticator or Authy). Not set up yet? Follow Step 1 below.
• Your current X4T password (if you log in with your email address and a password).
• Access to the inbox of your new email address. We send a confirmation code there.
• A permanent email address. Temporary or disposable email services are not accepted.

Good to know: You do not need access to your old email address. We only send a security notice there.

Step 1: Turn on two-factor authentication (if you haven't yet)

For your security, your email address can only be changed when 2FA is on. If it is already on, go straight to Step 2.

1. Log into your X4T account at app.x4t.com or in the X4T app.
2. Click the account icon in the top right corner and choose My Account.
3. Under Account settings, click Two-factor authentication.
4. Click Set up two-factor authentication.
5. Enter your password and click Continue.
6. • If you log in with Google or Apple, no password is needed here.
   • If you see Please log in again, click Log out and log in again. After logging in, you come back to this page automatically.
6. Open your authenticator app and add X4T as a new entry:

   
   

   Codes from an older X4T entry in your app will not work. Always use the new entry.

7. • scan the QR code shown on the screen, or
   • copy the Key for manual entry and paste it into the app (handy if the app is on the same phone).
7. Enter the 6-digit code that your app shows for X4T and click Turn on two-factor authentication.
8. Save your recovery code. It is shown only once and lets you log in if you ever lose access to your authenticator app. Keep it in a safe place, then click I saved it.

You will see the message "Two-factor authentication is on now. Your other sessions have ended." Other devices are logged out, so simply log in there again.

Shortcut: You can also start the 2FA setup from the Security page. Without 2FA, the E-mail address section shows a Set up two-factor authentication button instead of the form.

Step 2: Change your email address

1. Log into your X4T account.
2. Click the account icon in the top right corner and choose My Account.
3. Under Account settings, click Security: linked logins and e-mail address.
4. Scroll down to the E-mail address section.
5. Fill in the form:
6. • New e-mail address: the address you want to use from now on.
   • Your current password: the password you use to log in.
   • 6-digit code from your authenticator app: open your app and enter the current code for X4T.
6. Click Send the code.

   
   

   
   You will see: "If this address can be used, we have sent a 6-digit code to it." We also send a notice to your current address, with a link to stop the change in case it wasn't you.
7. Keep the X4T page open and go to the inbox of your new email address. Look for the email "Your e-mail change code" (please check your spam or junk folder too). The code is valid for 15 minutes and works only once.
8. Back on X4T, enter the code in the field Code from the e-mail.
9. Click Change e-mail address.

Done! You will see: "Your e-mail address is changed. Your other sessions have ended."

Important: If you close or reload the page before you enter the code, you need to start again from step 5. You can request an email change three times a day, and requests with a wrong password or code count too.

About the payout notice: Above the Change e-mail address button you will see a note that payouts are paused for 24 hours after this change, unless two-factor authentication was already set up before it. Because 2FA must be on before you can change your email address, payouts that you confirm with your authenticator app are not affected.

What happens after the change?

• Log in with your new email address from now on. Your password and your 2FA stay the same.
• All other devices are logged out for your security, including the X4T app on your phone. Simply log in again with your new address. The device you used for the change stays logged in.
• You receive a "Security notice for your account" at your old and at your new address, confirming the change.
• All emails from X4T now go to your new address.
• Your account stays the same: balances, wallets, trading history and identity verification (KYC) are not affected.
• Your old address is reserved for you for 30 days. Nobody else can use it during that time, and you can switch back to it if needed.

Do you log in with Google or Apple?

If you log in only with Google or Apple, your account has no password. In that case you change your contact e-mail, which is the address X4T writes to. Your login does not change: you keep logging in with the same Google or Apple account.

1. Make sure 2FA is on (see Step 1).
2. Go to My Account → Security: linked logins and e-mail address.
3. In the section Change contact e-mail, enter your New e-mail address and click Send the code.
4. A window Confirm with your authenticator app opens. Enter the 6-digit code from your app and click Confirm code.
5. Continue with steps 7 to 9 of Step 2: enter the code from the email and click Change e-mail address.

If you have also added a password to your account, you will see the normal form from Step 2 instead.

You didn't request this change?

Whenever someone requests a new email address for your account, we send a "Security notice for your account" to your current address. It contains a link to stop the change, valid for 7 days.

1. Open the link in the email.
2. On the page Stop the e-mail change, click This wasn't me.
3. The change is stopped. You are logged out on every device, and earlier password reset links no longer work.
4. Whoever requested the change knew your password and your authenticator code. So please, right away:
5. • click Choose a new password and set a new, strong password, and
   • set up two-factor authentication again.

If the change had already gone through, you will see Account secured. We have logged you out everywhere and informed our support team. Please contact support to get your account back.

Stay safe: Never share your password, your authenticator codes or the code from our email with anyone.
