Clicking a link then closing it is low risk on an updated device; danger comes from entering info or downloading files, not from briefly viewing a page.

A VPN hides your IP and encrypts traffic, but it does not stop malware, phishing, cookies, account tracking, weak passwords, or data breaches at websites.

Verification codes you didn't request usually mean someone is trying to log in with your password, or a scam wants the code. Never share it; change your password.

SIM swapping is when a scammer moves your phone number to their SIM to intercept your texts and 2FA codes, then take over your accounts. Add a carrier PIN.

A suspicious login alert means your email saw a sign-in from a new device or location. It is often you, but if not, change your password and turn on 2FA.

A passkey is a passwordless login that replaces your password with a secure key on your device, unlocked by fingerprint, face, or PIN, and resists phishing.

A firewall controls which network traffic can enter or leave your device or network, blocking unwanted connections while allowing the ones you trust.

Antivirus can slow your PC during full scans and updates because it checks files in real time. Learn why it happens and how to speed things up.

HTTPS means your connection to a website is encrypted, so data sent between you and the site cannot be read or changed by others on the network.

SIM not provisioned means your carrier has not yet activated the SIM on their network. Wait for activation, restart, or contact your carrier to fix it.
