- Choose your second factor: Google prompts (recommended), authenticator app, or security key
- Set up backup options (backup codes or a backup phone number)
Microsoft Account
- Go to account.microsoft.com/security
- Select "Advanced security options"
- Under "Two-step verification", click "Turn on"
- Follow the setup wizard to configure the Microsoft Authenticator app or another method
- Save your recovery code in a secure location
Apple ID

Addressing Common 2FA Concerns
"It's too inconvenient"
Modern 2FA is much less intrusive than you might think. Authenticator apps generate codes instantly, and many services remember trusted devices so you don't have to verify every single time. The few extra seconds it takes are insignificant compared to the hours or days you'd spend recovering a hacked account.
"What if I lose my phone?"
This is a legitimate concern, but it's easily addressed with proper preparation. When you set up 2FA, most services provide backup codes. These are one-time-use codes that let you access your account even without your second factor.
Backup Codes: Your Safety Net
- Save them immediately when they're generated during 2FA setup
- Store them securely - Print them and keep in a safe, or save in an encrypted password manager
- Don't store them digitally on your phone - If you lose your phone, you lose your backup codes too
- Regenerate them periodically - Some services allow you to invalidate old codes and generate new ones
- Consider multiple authenticator backups - Some apps like Authy allow cloud backups of your authenticator codes
"What if the service doesn't support 2FA?"
If a service doesn't support 2FA, that's a red flag about their security practices. Consider whether you truly need an account with that service, and if so, make sure to use a strong, unique password generated by a password generator or passphrase generator.
"SMS 2FA is better than nothing"
This is absolutely true. While SMS-based 2FA has known vulnerabilities (like SIM swapping attacks), it's still vastly more secure than having no second factor at all. If SMS is the only 2FA option available, use it. You can always upgrade to an authenticator app or hardware key later if the service adds support.
The Takeaway
Two-factor authentication is one of the single most impactful steps you can take to secure your online accounts. It's free, it's easy to set up, and it dramatically reduces the risk of unauthorized access.
Start with your most important accounts: email, banking, and social media. Once you've secured those, work through your other accounts. Most password managers can audit which of your accounts offer 2FA, making it easy to identify where to enable it next.
Don't wait until after an account is compromised to enable 2FA. Take 10 minutes today to secure your most important accounts—your future self will thank you.
