Lock screen can leak codes from SMS to scammers

By default, the smartphone shows the text of incoming messages directly on the locked screen. This is convenient, but dangerous: an outsider will see a one-time code that confirms the entrance to the bank, social networks, messengers or on public services. Knowing your phone number and card details, an attacker will be able to enter your personal account and get to the money. In addition to the code, the screen shows the balance of the account, the amount of payments and the delivery address. And the fraudster can request a password reset on the bank’s website and wait for the code to come to your phone.

Turning off the message display is easy. On Android, go to settings, open notifications, and choose to hide content on the lock screen. On the iPhone, in the notification settings, set the thumbnail display to "Never" - separately for messages.

Remember: if you call the code to an outsider and lose money, the bank will not compensate for the damage. Additionally, set a six-digit password and biometrics, connect the authenticator application, enable device search. If you lose your phone, immediately block the SIM card and call the bank.
