Two-Factor Setup Guide
Two-factor authentication (2FA) adds a second check — a code or tap — after your password. Pick a service below and follow the wizard. Your progress is saved in this browser, so you can come back any time.
Step 1 — Pick a service
Setup steps
Backup codes — read this before you start
- Most services give you backup or recovery codes when you turn on 2FA. Save them on paper and keep the paper somewhere safe — not in your phone notes.
- Backup codes work when your phone is lost, broken or replaced. Without them you can be locked out of your own account.
- Prefer an authenticator app over SMS codes. SMS codes can be stolen through SIM-swap fraud; authenticator apps cannot.
- Never share a 2FA code with anyone — not even someone who claims to be from the company. Real support never asks for your code.
- If you change your phone number, update 2FA on every account before the old SIM stops working.
Why 2FA matters
- Stolen passwords are the most common way accounts are hacked. A second factor blocks most of those attacks.
- It protects your email first — email can reset passwords for your bank, social media and everything else.
- Setup takes about five minutes per account and then it is done.
Common questions
- Is SMS code enough? It is much better than nothing, but an authenticator app is safer when it is offered.
- What if I lose my phone? Use your saved backup codes to log in, then move 2FA to your new phone.
- Does 2FA slow down login? Only by a few seconds — you enter a code or approve a tap after your password.
