Replace text message login codes with a free app such as Google Authenticator on your most important accounts. App-generated codes are more secure because they cannot be stolen, even if someone takes over your phone number.

Step-by-step guide

Download an authenticator app: Google Authenticator, Microsoft Authenticator, or Authy (Authy includes cloud backup of your codes).
Log in to your most important accounts one by one. Start with email, then banking, then social media.
Find the two-step verification or security settings section and look for 'Authenticator app' as an option.
Scan the QR code shown on screen with your authenticator app to link it.
Save the backup codes shown during setup. Store them separately from your device in case you ever lose your phone.

Why this matters

Text message codes can be intercepted by attackers who convince your mobile provider to transfer your phone number to a SIM card they control, a scam that is increasingly common in the UK. An authenticator app generates codes on your device only, so intercepting your SMS is no longer enough to break into your accounts.
