Password management
What is MFA?
Multi-factor authentication (MFA), also called Two-Step Verification (2SV), adds an extra layer of protection to your accounts. Instead of relying solely on a password, MFA requires a second verification method, like a code sent to your phone or an app, to confirm your identity.
Passwords alone can be stolen, guessed, or compromised. Adding MFA ensures that even if your password is hacked, your account remains secure.
Types of MFA
There are several types of MFA to choose from:
- SMS codes: A one-time code sent to your mobile phone via text message
- Authenticator apps: Apps like Google Authenticator or Microsoft Authenticator generate unique codes that refresh every 30 seconds
- Biometric authentication: Uses physical traits like fingerprints or facial recognition for verification
- Physical security keys: A small device you plug into your computer or phone to verify your identity.
Using more than one factor makes it much harder for attackers to access your accounts, even if they have your password.
