Why cyber safety matters

Cyber safety means using digital devices, accounts and online services in ways that reduce security, privacy and fraud risks.

Strong passwords

Use long, unique passwords or passphrases. Do not reuse the same important password across many sites. A password manager can help generate and store unique passwords.

Two-factor authentication

Two-factor authentication (2FA) adds another verification step beyond a password. Prefer strong methods such as authenticator apps or security keys when available.

Phishing

Phishing messages try to trick you into revealing information, opening malicious files or visiting fraudulent websites. Be cautious with urgent requests, unexpected links, spelling tricks and requests for passwords or one-time codes.

Protect personal information

Think before sharing

Do not publish private information just because a form or message asks for it.

Keep software updated

Updates often contain important security fixes.

Use screen locks

Protect phones and computers with a PIN, password or biometric lock.

Back up important data

Backups help you recover from device failure, accidental deletion or some attacks.

Never share an OTP, password or recovery code with someone who asks for it unexpectedly.
