What are the best practices for two-factor authentication?

The best practices for two-factor authentication (2FA) include using an authenticator app, enabling 2FA on all accounts, and keeping backup codes secure.

Why should I use an authenticator app instead of SMS?

Authenticator apps are generally more secure than SMS because they are less vulnerable to interception and phishing attacks.

What should I do if I lose my phone with the authenticator app?

If you lose your phone, use your backup codes to access your accounts and then reset your 2FA settings. It's also wise to have a recovery plan in place.

Can I use 2FA for all my online accounts?

Yes, most online services offer 2FA. It's recommended to enable it wherever possible to enhance your account security.

Are there any downsides to using two-factor authentication?

While 2FA significantly increases security, it can be inconvenient if you lose access to your second factor, like your phone or backup codes.
