When you set up your Argent wallet, you activated security notifications. Security notifications can help keep your wallet safe by giving you a chance to respond to an event.
We recognise that some people do not want to share their personal contact details. During the creation of a wallet, you can tap Can't receive text messages and skip the phone number step. You can also use a separate email address for your Argent wallet.
Please do make sure you are using the accessible email/phone number that you monitor daily.
