What is an Authenticator App?

An authenticator app is a security application that generates time-based, one-time passcodes (TOTPs) used for two-factor authentication. When you enable 2FA on your online accounts, you will typically receive a code via SMS or email. However, using an authenticator app is often more secure, as it doesn't rely on your mobile network or email account, which can be compromised. Instead, the codes are generated within the app on your device, making it a safer option for securing your accounts.
