Two-Factor Authentication (2FA) is an extra layer of security for your Airtm account. To log in you need two things: your password (something you know) and a temporary code generated on your phone (something you have). Even if someone gets your password, they can't access your account without that second factor.
What are Google Authenticator and Authy?
Google Authenticator and Authy are free apps that generate the 6-digit verification codes you need for 2FA. You can install either one from the App Store (iOS) or Google Play (Android). The choice is yours — both work equally well with Airtm.
