Two-step verification

This makes sure that even someone who knows your password cannot sign in without your device. We strongly recommend enabling it on an account that holds money.

Updated · Read 3min · Applies to v2026.08

What it does

When enabled, signing in requires a confirmation code in addition to your password. Someone who only has your password can no longer get in.

Turning it on

Open "Two-step verification" from the menu.

  1. Re-enter your password

    You confirm your current password to prove it is really you making the change.

  2. Approve by email

    A code is sent to your registered address. Enter it on screen.

  3. Then confirm by SMS

    SMS is sent only after the email step succeeds. The order is fixed — you cannot skip email and use SMS alone.

From your next sign-in onward, you will be asked for a code.

Turning it off

Use the same screen. Disabling also requires your password and a confirmation code.

Before you disable it

Disabling returns your account to a state where the password alone is enough to sign in. If you are changing phones, it is safer to set it up again on the new device than to leave it off.

If the code does not arrive

ProblemWhat to do
No emailCheck your spam folder, then use the resend button
No SMSCheck signal. SMS often fails to arrive while travelling abroad
Code rejectedIt has expired. Request a new one and use that

Resend is not available immediately. Wait before pressing it — pressing repeatedly does not send additional codes.

Lost device or changed number

If you can no longer receive SMS on your registered number, you cannot disable it yourself. Please open a support ticket.

We will ask you to confirm details such as your registered name, address and recent activity. This exists to stop someone taking over your account by claiming to have lost a device, so please allow time for the checks.
