The Authenticator App Pro, a free two-factor authentication tool, generates push authentication and time-based one-time passwords (TOTP). Multi Factor Authenticator is maintaining the security of your online accounts on websites that use TOTP.

Since the created codes are one-time tokens, they increase the level of security for your online accounts. You may safeguard your account by simply scanning a QR code. Using 2FA Authenticator on websites that allow TOTP helps protect your online accounts. Your account will be configured to use Mobile Authenticator for TOTP authentication. To use the 2FA Authenticator, all you have to do is copy the code and paste it into your account. All done!
