A caller poses as support and persuades someone to reveal a code · The caller uses a claimed identity to persuade a person to reveal a code. This is social engineering.
Open the official app yourself without sending secrets · The sender is asking for an account secret. Check through the official app or website without sending the sender a password or code.
False · Laptop antivirus checks the laptop for malicious software. The network owner manages router access through the router's settings and credentials.
Request a remote lock through the official service · Use a trusted device to request a lock through the official service. Delivery depends on the device and connection, so the request does not guarantee an immediate lock.
Ask the owner to change the Wi-Fi password · Changing the password replaces the exposed credential. The owner should also follow the router's instructions to disconnect unauthorised devices and reconnect trusted ones.
A long random password generated by a password manager · Length and unpredictability both help. Personal details and familiar sayings remain predictable despite punctuation or capitals.
The person has a password they can try against Tom's email · The exposed Wi-Fi password is also Tom's email password. Other safeguards may still block access, but reuse gives the person a credential to try.
A guessed or leaked password could expose the linked account · Remote phone protection does not remove the linked account's need for protection. A predictable or leaked password puts that account at risk.
