How to Set Up Two-Factor Authentication on Your Devices

1. What Is Two-Factor Authentication (2FA)?

Two-Factor Authentication adds an extra step when logging in.
You enter:

1. Your password

2. A code sent to your phone or generated by an app

Even if someone has your password, they can’t get in without your phone or code.

2. Why 2FA Is Important

• Protects against hackers

• Stops unauthorized logins

• Adds a second layer of security

• Required by many apps (banking, email, etc.)

3. Common 2FA Methods

• SMS Codes – Sent to your phone number

• Authenticator Apps – Generate secure codes (Google Authenticator, Microsoft Authenticator, Authy)

• Security Keys – Physical USB devices for high-level security
