Why this matters

Most account incidents start with a weak or reused password or with a phishing link. This page helps you set up 2FA, keep unique strong passwords, and act quickly if something goes wrong.

2FA options — quick comparison

Method	Strength	Pros	Considerations
TOTP app (time-based codes)	High	Works offline; widely supported	Keep backup codes; plan for device loss
Hardware key (FIDO/U2F)	Very High	Phishing-resistant; one-tap	Register at least two keys; device compatibility
Push approval	High	Simple approve/deny	Beware “fatigue” prompts; secure device & screen lock
SMS codes	Medium	Easy to start	SIM-swap risk; keep as fallback, not primary

Recommendation: Prefer TOTP or hardware key; keep SMS only as a backup.

Set-up (TOTP) — 4 steps

Install a reputable authenticator app on your phone.
Open your account’s Security → Two-Factor; scan the QR code.
Enter the 6-digit code to confirm.
Download/print backup codes and store offline.

Set-up (Hardware key) — 4 steps

Get a compatible security key (USB/NFC).
Add it via Security → Security keys.
Register two keys (primary + spare).
Keep backup codes in a safe place.

Password hygiene — habits that stick

Length: Aim for 12–16+ characters (more for critical accounts).
Uniqueness: Never reuse passwords across sites.
Manager: Use a password manager to generate/store strong, unique passwords.
Passphrases: Consider long, memorable multi-word phrases.
Change when necessary: If compromise is suspected, change immediately (no need for arbitrary monthly changes).
No sharing: If sharing access is unavoidable, use your manager’s secure sharing feature (not chat/email).

Backup codes & recovery

Generate backup codes during 2FA setup; store offline (paper or secure vault).
If you lose your phone or key, use a backup code, then re-enrol 2FA on the new device.
Review recovery email/phone settings and keep them current.

Device & session security

Sign out everywhere after any incident; review active devices/sessions periodically.
Keep OS, browser and extensions up to date; remove what you don’t use.
Prefer official apps/stores; avoid sideloading unknown APKs/add-ons.
On shared/ public devices, use a private window and sign out when finished.

Breach action plan — first 30 minutes

Change the password (start with email, banking and the password manager).
Enable/strengthen 2FA (TOTP or hardware key).
Sign out everywhere (revoke unrecognised devices).
Check mail filters/forwarding for unknown rules.
Confirm recovery email/phone.
Scan the device with updated anti-malware.
Review/remove risky extensions/apps.
Re-check the site via manual URL + certificate (🔒) details.
Enable security alerts (logins, password changes).
Note what happened and adjust filters to block repeats.

Short FAQ (informational only)

Is SMS 2FA enough?

It’s better than nothing, but TOTP/hardware keys are stronger. Keep SMS as a fallback.

Lost my phone — no codes. What now?

Use any registered spare key, recovery method, or provider support you typed manually. Afterwards, re-enrol 2FA and create new backup codes.

Do I need to rotate passwords regularly?

Rotate after incidents or when risk changes. Focus on uniqueness + length + 2FA.

Can a password manager be trusted?

Choose a reputable one, secure it with a strong master password and 2FA, and keep software up to date.
